Mastodon

Social · mastodon.social
Decentralized federated social network
Last checked Last changed
★★★★☆ fairly user-friendly

The policy emphasizes minimal monetization, short log retention, and user controls like archive download and account deletion. The main caveat is the inherent exposure of federated messaging and the public nature of much of the platform.

Mastodon.social’s legal posture is relatively privacy-conscious compared with many social platforms: it says it does not sell personal information, limits server log retention, allows content export, and lets users delete accounts. At the same time, because it is a federated social network, posts may be copied to other servers, and direct or followers-only messages can still be viewed by server operators and recipients.

Points of interest

negative ●●●●○ from: privacy
Private posts can spread

Followers-only and direct posts may be stored on other servers, and the policy warns that server operators or recipients may view, screenshot, copy, or resh​are them. In practice, these messages are not treated as truly private.

"the operators of the server and any receiving server may view such messages, and that recipients may screenshot, copy or otherwise re-share them."
negative ●●●●○ from: privacy
Logs keep IPs up to a year

The service records your login IP address and says the latest IP address used may be stored for up to 12 months. That is a meaningful amount of identity-linked metadata retention.

"The latest IP address used is stored for up to 12 months."
positive ●●●●○ from: privacy
No data selling

The policy says Mastodon does not sell or trade your personal information. That reduces the risk of ad-tech style sharing or monetization of your data.

"We do not sell, trade, or otherwise transfer to outside parties your personally identifiable information."
positive ●●●●○ from: privacy
Export your content

You can request and download an archive of your content, including posts, media, and profile images. This makes it easier to back up your data or move on from the service.

"You can request and download an archive of your content, including your posts, media attachments, profile picture, and header image."
positive ●●●●○ from: privacy
Account deletion available

The policy says you may irreversibly delete your account at any time. That gives users a clear exit path, though deletion is permanent.

"You may irreversibly delete your account at any time."
negative ●●●○○ from: privacy
Cookies track account use

Cookies are used to recognize your browser and associate it with your account, as well as save preferences. This is standard, but it does mean persistent browser tracking on the site.

"These cookies enable the site to recognize your browser and, if you have a registered account, associate it with your registered account."
positive ●●●○○ from: privacy
Short server log retention

Server logs containing IP addresses are retained, if kept at all, for no more than 90 days. That is a relatively limited retention period for operational logs.

"Retain server logs containing the IP address of all requests to this server... no more than 90 days."
