Wikipedia vs Medium

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.

Most disputes must go to individual binding arbitration, and you waive class actions unless you opt out within 30 days. This makes it harder to sue in court or join with other users over small-value claims.

If Medium harms you, its financial exposure is heavily limited. Most claims are capped at the greater of $50 or the amount you paid, which can leave users undercompensated.

Medium expressly says it does not sell personal information. That is a meaningful privacy protection compared with services that monetize user data through sale or sharing arrangements.

Users can access, correct, delete, and export account information through Settings. Self-service controls make it easier to leave the service or review what Medium holds about you.

You keep ownership of what you post, but you grant Medium a worldwide, sublicensable, royalty-free license to use and display it within the service. That is common for hosting platforms, but still gives Medium broad operational rights over your content.

Medium may remove content or suspend or terminate accounts at its discretion. For users who rely on the platform, that creates platform-dependence risk with limited recourse.

Medium tracks reading history, clicks, device data, and uses cookies plus third-party analytics to analyze behavior and target content to your interests. This means substantial behavioral monitoring beyond simple account operation.

For covered users, Medium says closed-account data will be deleted within 14 days. A specific deletion timeline is more user-friendly than an open-ended retention promise.

Medium says it will notify you about legal-process disclosures so you can challenge them, unless prohibited or safety concerns apply. It also says it will object to improper requests.

Your information may be processed in the United States and other countries where protections may differ from your home jurisdiction. This can reduce practical control or change the legal safeguards that apply.

Third-party embeds on Medium pages can send those companies information about your activity as if you visited them directly. Medium says it does not control what those third parties collect through embeds.
