Substack vs Wikipedia

Most disputes must be resolved through individual arbitration in San Francisco County, and you waive class or representative actions. This makes collective claims and court litigation harder for users.

You keep ownership of your posts, but Substack gets a royalty-free, perpetual, irrevocable, worldwide license to use and distribute them. That license can continue even after you stop using the service.

If something goes wrong, Substack broadly disclaims warranties and caps most liability at the greater of $100 or what you paid in the prior 12 months. Users may have very limited practical recourse for losses.

Substack can suspend or terminate your account for any reason at its discretion, sometimes without notice. Public posts may also remain available after account deletion.

Substack shares personal information with affiliates, creators, service providers, integrated third parties, buyers in a business transfer, and authorities when required. Creator interactions may also be governed by the creator’s own privacy practices rather than Substack’s.

Substack says it may collect information about your online activity after you leave its site, and it does not honor Do Not Track signals. Users who want minimal tracking do not get that by default.

Substack states that users may request access, correction, deletion, restriction, portability, and objection, and says it will respond within one month. These are meaningful user controls, especially for EEA/UK-style privacy rights.

You may have to cover Substack’s costs, damages, and attorneys’ fees for third-party claims tied to your use of the platform or violations of the terms. This can shift substantial legal risk onto users.

Direct messages are not end-to-end encrypted, and Substack personnel may access them for support, safety, or enforcement. Users should not treat Substack DMs as a secure messaging channel.

You can edit some profile data and delete your account from account settings without needing to contact support. This is a practical and user-friendly control, even though some public content may persist.

Substack expressly says original content you post remains yours. That is better than terms that claim ownership outright, even though the platform still takes a very broad license.

Substack says marketing emails are based on consent where required and can be unsubscribed from at any time. This is a basic but useful control over promotional communications.

Anything you contribute is generally public and forms a permanent record tied to your username or temporary account. This can create lasting privacy and reputational consequences.

You can read and even edit without a standard account, and a normal account usually needs only a username and password. This materially lowers the amount of personal data you must hand over to participate.

Wikimedia expressly says it does not sell your information or share it for third-party marketing. That is a strong privacy commitment compared with many ad-supported platforms.

Photos or videos may include device metadata such as time and location, and that can become public unless you change your device settings. Users can accidentally reveal where or when media was created.

If you contribute content you own, you generally license it for broad public reuse under free licenses and cannot later unilaterally revoke that permission. In practice, you give up control over future reuse of your contributions.

The policy says personal information is kept only as long as reasonably needed and is often deleted, aggregated, or de-identified after 90 days. This is a meaningful retention limit for nonpublic data.

Users can request access, correction, restriction or objection, deletion-related help, and a copy of their data for transfer. Some data controls and downloads are also available directly in account settings.

Legal claims against Wikimedia generally must be brought in San Francisco County under California law, and claims may need to be filed within one year if that is earlier than otherwise allowed. This can make disputes harder for non-California users.

Wikimedia provides the service and content without warranties of accuracy, safety, availability, or fitness for a particular purpose. If information is wrong or the service fails, your remedies may be limited.

Substantial privacy policy changes get advance notice and a 30-day public comment period. This is more transparent than silent or immediate policy updates.

The service uses cookies, local storage, JavaScript, and tracking pixels for security, analytics, and functionality, but says it will not use third-party cookies without permission. This is less aggressive than many sites, though still not tracking-free.
