mastodon.social privacy policy — score 25/100 (high risk)
Last analyzed
Mastodon GmbH · mastodon.social
Report details
high riskMastodon GmbH's mastodon.social privacy policy page was not actually provided for analysis — only navigation chrome and marketing copy were included, making it impossible to assess compliance and leaving users without verifiable assurances.
The provided text contains only the website's navigation structure, footer links, and marketing taglines for mastodon.social, operated by Mastodon GmbH. The actual privacy policy content linked at /privacy-policy was not captured in the scrape. No substantive privacy language, data processing details, legal bases, user rights, or transfer mechanisms are present in the provided text. This means the analysis can only flag the absence of information rather than evaluate existing protections.
Category Assessment
Breakdown of the policy across key compliance areas. Good = strong, fair = mixed, poor = concerning.
No policy text was provided, so there is no evidence of data minimization commitments or collection limits.
The privacy policy page link exists but its content was not captured, meaning transparency cannot be verified from the provided text.
Zero information available about subprocessors, analytics providers, or any third-party data recipients in the provided content.
No mention of data residency, transfer mechanisms, or geographic processing locations anywhere in the provided text.
Silent — no language about whether user data is used for AI training, and no opt-out mechanism described.
No GDPR user rights (access, deletion, portability, objection) are documented in the provided text.
Key Findings
Notable clauses, issues, or positive practices discovered (critical first)
Privacy policy content entirely missing from provided text
The linked privacy policy page at /privacy-policy was included in the scrape but only rendered navigation chrome and marketing copy — no substantive privacy language appeared. This makes it impossible to assess what data is collected, how it is processed, or what rights users have.
No data processing details or legal bases stated
The provided text contains no information about what personal data mastodon.social collects, the legal bases under GDPR Article 6, or purposes of processing. This is a fundamental transparency failure if the policy itself is not accessible or readable.
Fediverse data sharing implications unaddressed
Mastodon.social is part of the fediverse, meaning user data (posts, profiles, interactions) is federated to other independent servers. The provided text does not explain this cross-server data flow, its privacy implications, or how users can control it — a significant gap for a decentralized social network.
Marketing claims about privacy lack substantiation
The page states 'No algorithms, ads, or clickbait in sight' as a privacy-positive differentiator, but without an accessible privacy policy, these claims are unverifiable and potentially misleading under GDPR transparency requirements.
Consumer Takeaway
You cannot evaluate mastodon.social's privacy practices from this text because the actual policy content is missing; visit the privacy policy page directly and review it before trusting the service with your data.
Compliance Posture
Unknown and unverifiable — the privacy policy content was not provided, so no compliance assessment can be made. This itself is a concern if the policy is not easily accessible or renderable.
EU Transfers
No information provided about data storage locations, international transfers, or safeguard mechanisms such as Standard Contractual Clauses.
