Overview

This page covers Tumblr’s Terms of Service across 14 scrapes spanning 2022-07-11 to 2026-01-17, with 20 unique snippets, most newly captured at the 2022-07-11 baseline. Tumblr_Community_Guidelines.jsonl and Tumblr_Privacy_Policy.jsonl are both empty (0 lines) and have been skipped.

Tumblr’s Content-license language is notably more transparent and self-limiting than most platforms tracked in this wiki: the “User Content License to Tumblr” clause grants a “non-exclusive, worldwide, royalty-free, sublicensable, transferable right and license… to create derivative works of” User Content, but explicitly clarifies that “the reference in this license to ‘creat[ing] derivative works’ is not intended to give Tumblr a right to make substantive editorial changes,” instead existing specifically to enable reblogging. A reciprocal “Content License to You” clause grants users a license to redistribute and create derivative works of other users’ Content, also strictly for reblogging purposes — meaning Tumblr’s reblog ecosystem is implemented as two mirrored licenses (Tumblr-from-users, users-from-Tumblr) rather than one combined user-to-user grant as seen elsewhere in this wiki. Tumblr also discloses that deleted Content “may persist in caches or backups” and that “copies of or references to the User Content may not be entirely removed… due to the nature of reblogging” — a reblog-chain persistence risk similar in spirit to Threads’ fediverse persistence disclosure.

A separate “Custom Themes” clause creates a niche user-to-user grant: a Theme creator who stops distributing a Custom Theme cannot revoke it from Users already using it — “you hereby grant those Users an irrevocable license to use those Custom Themes as contributed by you.”

Flagged Keywords & Risks

• royalty-free, sublicensable, derivative works, create derivative, transferable — Tag the mirrored Content-license clauses (Tumblr’s license from users, and the matching license back to users) that together power reblogging. Why it matters: even though these licenses are framed narrowly, as existing just to enable reblogging, the underlying grant is still broad — sublicensable and transferable. And because Tumblr discloses that deleted content can persist, it may live on indefinitely in other users’ reblog chains.
• assignable — A “Miscellaneous” clause: the Agreement “is not assignable, transferable, or sublicensable by you except with Tumblr’s prior written consent. Tumblr may assign this Agreement… without your consent.” Why it matters: this is the standard one-sided setup also seen on Spotify’s Terms of Service — Tumblr can hand off its rights and obligations to someone else freely, but you can’t do the same with yours.
• irrevocable — A narrow user-to-user grant over Custom Themes: once other Users have adopted a Theme, the original creator can’t revoke their access, even after pulling the Theme from distribution. Why it matters: this is a genuine irrevocable grant, but an unusual one — it runs from one user to another, not from user to platform, which sets it apart from every other irrevocable clause in this wiki.
• sublicense — Discloses that Tumblr Live (a livestreaming feature) is “powered by TMG,” with Tumblr sharing user data — username, profile photo, “about me,” and approximate location — with this third-party operator, who controls that data for the feature. Why it matters: this is a concrete disclosure of third-party data-sharing — it names the operator (TMG) and lists the exact data categories shared, tied to one specific feature.
• scrape — A “Limitations on Automated Use” clause: bans accessing the Services “by any means (automated or otherwise)” outside Tumblr’s published interfaces, “unless permitted by Tumblr’s robots.txt file,” and separately bans scraping Content. Why it matters: a standard anti-scraping restriction that defers to the site’s robots.txt file (the standard file websites use to tell automated crawlers what they can and can’t access) — similar in structure to Reddit’s and YouTube’s scraping rules.

Legal Context & Research Significance

The disclosed reblog-chain persistence risk — that deleted Content “may persist in caches or backups” and that “copies of or references to the User Content may not be entirely removed… due to the nature of reblogging” — places this clause within wearetosed’s “data retention” category, since Tumblr’s own architecture means effective retention extends beyond the platform’s direct control once content has been reblogged by other users. The robots.txt-aware “Limitations on Automated Use” clause is the same enforceability structure Atkinson (2025) describes: a scraper that traverses this page has actual notice of the scraping ban, supporting a contract-breach claim, even though, as Atkinson notes, “robots.txt is a leaky solution” that “cannot enforce itself” technically. The Custom Themes irrevocable creator-to-user grant is a narrower instance of wearetosed’s “rights & liability waivers” category, since once a Theme is adopted, the original creator permanently loses the ability to revoke access even after withdrawing it from distribution.

Clause: royalty-free, sublicensable, derivative works, create derivative, transferable

Content and User Content ---------------------------- Definitions: For purposes of this Agreement: (1) the term “Content” means a creative expression and includes, without limitation, video, audio, photographs, images, illustrations, animations, logos, tools, written posts, replies, comments, information, data, text, software, scripts, executable files, graphics, Themes (as defined below), and interactive features, any of which may be generated, provided, or otherwise made accessible on or through the Services; (2) the term “User Content” means Content that you or any other user of the Services (collectively, a “User”) submits, transfers, or otherwise provides to the Services. Content includes, without limitation, all User Content. Your Rights in User Content: Users retain ownership and/or other applicable rights in User Content, and Tumblr and/or third parties retain ownership and/or other applicable rights in all Content other than User Content. You retain ownership you have of any intellectual property you post to Tumblr. User Content License to Tumblr: When you provide User Content to Tumblr through the Services, you grant Tumblr a non-exclusive, worldwide, royalty-free, sublicensable, transferable right and license to use, host, store, cache, reproduce, publish, display (publicly or otherwise), perform (publicly or otherwise), distribute, transmit, modify, adapt (including, without limitation, in order to conform it to the requirements of any networks, devices, services, or media through which the Services are available), and create derivative works of, such User Content. The rights you grant in this license are for the limited purposes of allowing Tumblr to operate the Services in accordance with their functionality, improve and promote the Services, and develop new Services. The reference in this license to “creat[ing] derivative works” is not intended to give Tumblr a right to make substantive editorial changes or derivations, but does, for example, enable reblogging, which allows Tumblr Users to redistribute User Content from one Tumblr blog to another in a manner that allows them to add their own text or other Content before or after your User Content. When you upload your creations to Tumblr, you’re giving us permission to make them available in all the ways you would expect us to (for example, via your blog, RSS, the Tumblr Dashboard, etc.). We never want to do anything with your work that surprises you.

Clause: sublicensable, derivative works, create derivative, transferable

One thing you should consider before posting: When you make something publicly available on the Internet, it becomes practically impossible to take down all copies of it. You also agree that you will respect the intellectual property rights of others, and represent and warrant that you have all of the necessary rights to grant us this license for all User Content you provide. Tumblr may add its own affiliate code to links posted on Tumblr at its discretion, provided a user has not previously included their own affiliate code into the applicable link. Users may opt out of this functionality here. Content License to You: As a User of the Services, Tumblr grants you a worldwide, revocable, non-exclusive, non-sublicensable, and non-transferable license to download, store, view, display, perform, redistribute, and create derivative works of Content solely in connection with your use of, and in strict accordance with the functionality and restrictions of, the Services (including, without limitation, Paid Services, as defined below). This means, for example, that we license Content to you for purposes of reblogging. Compliance with Community Guidelines: You agree that you won’t violate Tumblr’s Community Guidelines. Termination and Deletion: On termination of your Account, or upon your deletion of particular pieces of User Content from the Services, Tumblr shall make reasonable efforts to make such User Content inaccessible and cease use of it and, if required by the applicable Privacy Policy, delete your Account data and / or User Content unless permitted or required to keep this data in accordance with law; however, you acknowledge and agree that: (a) deleted User Content may persist in caches or backups for a reasonable period of time and (b) copies of or references to the User Content may not be entirely removed (due to the nature of reblogging, for example). You can delete your account at any time here.

Clause: sublicensable, transferable, assignable

This Agreement replaces all prior or contemporaneous understandings or agreements, written or oral, regarding the subject matter hereof and constitutes the entire and exclusive agreement between the parties. The failure of either party to exercise, in any way, any right provided for herein shall not be deemed a waiver of any further rights hereunder. If any provision of this Agreement is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that this Agreement shall otherwise remain enforceable and in full force and effect. This Agreement is not assignable, transferable, or sublicensable by you except with Tumblr’s prior written consent. Tumblr may assign this Agreement in whole or in part at any time without your consent. No agency, partnership, joint controllership, joint venture, or employment is created as a result of this Agreement and you do not have any authority of any kind to bind Tumblr in any respect whatsoever. Any notice to Tumblr that is required or permitted by this Agreement shall be in writing and shall be deemed effective upon receipt, when delivered in person by nationally recognized overnight courier or mailed by first class, registered or certified mail, postage prepaid, to Tumblr, Inc. (Automattic) 60 29th Street #343 San Francisco, CA 94110 Attn: Legal Department 20. Special Provisions for Users Located Outside of the United States ---------------------------------------------------------------------- Tumblr provides global products and services and enables a global community for individuals to share and follow the things they love.

Clause: derivative works

Your Rights in User Content: Users retain ownership and/or other applicable rights in User Content, and Tumblr and/or third parties retain ownership and/or other applicable rights in all Content other than User Content. You retain ownership you have of any intellectual property you post to Tumblr. User Content License to Tumblr: When you provide User Content to Tumblr through the Services, you grant Tumblr a non-exclusive, worldwide, royalty-free, sublicensable, transferable right and license to use, host, store, cache, reproduce, publish, display (publicly or otherwise), perform (publicly or otherwise), distribute, transmit, modify, adapt (including, without limitation, in order to conform it to the requirements of any networks, devices, services, or media through which the Services are available), and create derivative works of, such User Content. The rights you grant in this license are for the limited purposes of allowing Tumblr to operate the Services in accordance with their functionality, improve and promote the Services, and develop new Services. The reference in this license to “creat[ing] derivative works” is not intended to give Tumblr a right to make substantive editorial changes or derivations, but does, for example, enable reblogging, which allows Tumblr Users to redistribute User Content from one Tumblr blog to another in a manner that allows them to add their own text or other Content before or after your User Content. When you upload your creations to Tumblr, you’re giving us permission to make them available in all the ways you would expect us to (for example, via your blog, RSS, the Tumblr Dashboard, etc.). We never want to do anything with your work that surprises you. Something else worth noting: Countless Tumblr blogs have gone on to spawn books, films, albums, brands, and more. Any royalties or reimbursement you get for your creations are, needless to say, entirely yours.

Clause: transferable, assignable

Miscellaneous ------------------ This Agreement, as modified from time to time, constitutes the entire agreement between you and Tumblr with respect to the subject matter hereof. This Agreement replaces all prior or contemporaneous understandings or agreements, written or oral, regarding the subject matter hereof and constitutes the entire and exclusive agreement between the parties. The failure of either party to exercise, in any way, any right provided for herein shall not be deemed a waiver of any further rights hereunder.

Clause: irrevocable

Purchased Premium Themes may not be transferred between Accounts, between blogs, or between Services on a single Account and are subject to the payment terms herein. Tumblr grants you a license to customize the Tumblr Template Code to create your own Themes for use on your blog page (each a “Custom Theme”). If you choose, you may also contribute your Custom Themes for use by other Users as User Content. However, as a condition of this license allowing you to create Custom Themes, you agree that you won’t distribute such Custom Themes from locations other than Tumblr-owned or approved websites without our permission, as set out in our Community Guidelines. Note also that other Users may use your Custom Themes after you have removed them from distribution, and you hereby grant those Users an irrevocable license to use those Custom Themes as contributed by you. In other words, you can remove and stop distribution of your Custom Themes, but Users who are already using them can keep using them. To develop and distribute Custom Themes that are Premium Themes, please contact us. 10. Paid Services ------------------ Some of the Services require payment of fees (the “Paid Services,” including without limitation Premium Themes, Subscriptions, and Post+).

Clause: scrape

Tumblr is an ever-evolving platform. With new products, services, and features launching all the time, we need flexibility to make changes, impose limits, and occasionally suspend or terminate certain offerings (like features that flop). We can also terminate or suspend any account at any time. That sounds harsh, but we only use that power when we have a reason, as outlined in these Terms of Service, our Privacy Policy , and our Community Guidelines. Limitations on Automated Use: You may not, without express prior written permission, do any of the following while accessing or using the Services: (a) tamper with, or use non-public areas of the Services, or the computer or delivery systems of Tumblr and/or its service providers; (b) probe, scan, or test any system or network (particularly for vulnerabilities), or otherwise attempt to breach or circumvent any security or authentication measures; (c) access or search or attempt to access or search the Services by any means (automated or otherwise) other than through our currently available, published interfaces that are provided by Tumblr (and only pursuant to those terms and conditions) or unless permitted by Tumblr’s robots.txt file or other robot exclusion mechanisms; (d) scrape the Services, and particularly scrape Content (as defined below) from the Services; (e) use the Services to send altered, deceptive, or false source-identifying information, including without limitation by forging TCP-IP packet headers or email headers; or (f) interfere with, or disrupt, (or attempt to do so), the access of any other user of the Services, host or network, including, without limitation, by sending a virus to, spamming, or overloading the Services, or by scripted use of the Services in such a manner as to interfere with or create an undue burden on the Services. Don’t do bad things to Tumblr or to other users. Some particularly egregious examples of “bad things” are listed in this section. 4. Registration, Tumblr URLs, and Security ------------------------------------------- As a condition to using certain of the Services and in order for us to provide them to you, you may be required to create an account (an “Account”), provide your age and an email address and select a password and Tumblr username, which will serve as a default link to your default Tumblr blog of the form [username].tumblr.com (a “Tumblr URL”).

Users may opt out of this functionality here. Content License to You: As a User of the Services, Tumblr grants you a worldwide, revocable, non-exclusive, non-sublicensable, and non-transferable license to download, store, view, display, perform, redistribute, and create derivative works of Content solely in connection with your use of, and in strict accordance with the functionality and restrictions of, the Services (including, without limitation, Paid Services, as defined below). This means, for example, that we license Content to you for purposes of reblogging. Compliance with Community Guidelines: You agree that you won’t violate Tumblr’s Community Guidelines. These Guidelines provide information on a few categories of content that are damaging to our community. If you violate the Guidelines, you may not be able to continue using Tumblr.

Clause: scrape

Tumblr is an ever-evolving platform.

We can also terminate or suspend any account at any time. That sounds harsh, but we only use that power when we have a reason, as outlined in these Terms of Service, our Privacy Policy, and our Community Guidelines. Limitations on Automated Use: You may not, without express prior written permission, do any of the following while accessing or using the Services: (a) tamper with, or use non-public areas of the Services, or the computer or delivery systems of Tumblr and/or its service providers; (b) probe, scan, or test any system or network (particularly for vulnerabilities), or otherwise attempt to breach or circumvent any security or authentication measures; (c) access or search or attempt to access or search the Services by any means (automated or otherwise) other than through our currently available, published interfaces that are provided by Tumblr (and only pursuant to those terms and conditions) or unless permitted by Tumblr’s robots.txt file or other robot exclusion mechanisms; (d) scrape the Services, and particularly scrape Content (as defined below) from the Services; (e) use the Services to send altered, deceptive, or false source-identifying information, including without limitation by forging TCP-IP packet headers or email headers; or (f) interfere with, or disrupt, (or attempt to do so), the access of any other user of the Services, host or network, including, without limitation, by sending a virus to, spamming, or overloading the Services, or by scripted use of the Services in such a manner as to interfere with or create an undue burden on the Services. Don’t do bad things to Tumblr or to other users. Some particularly egregious examples of “bad things” are listed in this section.

One thing you should consider before posting: When you make something publicly available on the Internet, it becomes practically impossible to take down all copies of it. You also agree that you will respect the intellectual property rights of others, and represent and warrant that you have all of the necessary rights to grant us this license for all User Content you provide. Tumblr may add its own affiliate code to links posted on Tumblr at its discretion, provided a user has not previously included their own affiliate code into the applicable link. Users may opt out of this functionality here. Content License to You: As a User of the Services, Tumblr grants you a worldwide, revocable, non-exclusive, non-sublicensable, and non-transferable license to download, store, view, display, perform, redistribute, and create derivative works of Content solely in connection with your use of, and in strict accordance with the functionality and restrictions of, the Services (including, without limitation, Paid Services, as defined below). This means, for example, that we license Content to you for purposes of reblogging. Compliance with User Guidelines: You agree that you won’t violate Tumblr’s User Guidelines. These Guidelines provide information on a few categories of content that are damaging to our community. If you violate the Guidelines, you may not be able to continue using Tumblr.

Clause: irrevocable

Purchased Premium Themes may not be transferred between Accounts, between blogs, or between Services on a single Account and are subject to the payment terms herein. Tumblr grants you a license to customize the Tumblr Template Code to create your own Themes for use on your blog page (each a “Custom Theme”). If you choose, you may also contribute your Custom Themes for use by other Users as User Content. However, as a condition of this license allowing you to create Custom Themes, you agree that you won’t distribute such Custom Themes from locations other than Tumblr-owned or approved websites without our permission, as set out in our User Guidelines. Note also that other Users may use your Custom Themes after you have removed them from distribution, and you hereby grant those Users an irrevocable license to use those Custom Themes as contributed by you. In other words, you can remove and stop distribution of your Custom Themes, but Users who are already using them can keep using them. To develop and distribute Custom Themes that are Premium Themes, please contact us. 10. Paid Services ------------------ Some of the Services require payment of fees (the “Paid Services,” including without limitation Premium Themes, Blaze, and Subscriptions).

Clause: scrape

Tumblr is an ever-evolving platform. With new products, services, and features launching all the time, we need flexibility to make changes, impose limits, and occasionally suspend or terminate certain offerings (like features that flop). We can also terminate or suspend any account at any time. That sounds harsh, but we only use that power when we have a reason, as outlined in these Terms of Service, our Privacy Policy, and our User Guidelines. Limitations on Automated Use: You may not, without express prior written permission, do any of the following while accessing or using the Services: (a) tamper with, or use non-public areas of the Services, or the computer or delivery systems of Tumblr and/or its service providers; (b) probe, scan, or test any system or network (particularly for vulnerabilities), or otherwise attempt to breach or circumvent any security or authentication measures; (c) access or search or attempt to access or search the Services by any means (automated or otherwise) other than through our currently available, published interfaces that are provided by Tumblr (and only pursuant to those terms and conditions) or unless permitted by Tumblr’s robots.txt file or other robot exclusion mechanisms; (d) scrape the Services, and particularly scrape Content (as defined below) from the Services; (e) use the Services to send altered, deceptive, or false source-identifying information, including without limitation by forging TCP-IP packet headers or email headers; or (f) interfere with, or disrupt, (or attempt to do so), the access of any other user of the Services, host or network, including, without limitation, by sending a virus to, spamming, or overloading the Services, or by scripted use of the Services in such a manner as to interfere with or create an undue burden on the Services.
