Legion ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains what information we collect when you use the Legion mobile application ("App"), how we use it, and your rights regarding your data. By creating an account, you agree to the practices described in this policy.
1. Information We Collect
We collect the following categories of information:
Account & Profile InformationWhen you register, we collect your name, email address, date of birth, and gender. You may optionally provide a profile photo and a short bio. This information is stored in our database and used to create and identify your account.
User ContentWe collect and store content you create on Legion, including posts, comments, replies, and messages. This content is associated with your account.
Usage DataWe collect information about how you interact with the App, such as the communities you join, posts you view, and features you use. This helps us operate and improve the service.
Device InformationWe may collect basic device information such as operating system version and app version for the purpose of diagnosing technical issues. We do not collect precise device identifiers or fingerprinting data.
CommunicationsIf you contact us for support or submit a bug report, we retain the content of that communication to assist you.
2. How We Use Your Information
We use the information we collect to:
• Create and maintain your account
• Operate and deliver the features of the App, including posts, comments, communities, messaging, and networking
• Personalise your feed based on the communities you join
• Enforce our Terms and Conditions, including age restrictions and content moderation
• Respond to your support requests and bug reports
• Send you in-app notifications relevant to your activity (e.g. replies, mentions)
• Improve and develop the App
• Comply with applicable legal obligations
3. How We Share Your Information
We do not sell your personal data. We may share your information in the following limited circumstances:
Service ProvidersWe use third-party services to operate the App. These providers process data on our behalf and are contractually bound to protect it:
• Supabase — database, authentication, and file storage (supabase.com)
• Anthropic — AI responses generated by the @legion feature (anthropic.com)
• Expo / Expo Application Services — app build and delivery infrastructure (expo.dev)
Community Leaders & ModeratorsLegion community leaders and platform administrators may see your profile information and content as part of moderating communities you participate in.
Other UsersYour username, profile photo, bio, posts, and comments are visible to other users of the App. Messages are visible only to you and the recipient.
Legal RequirementsWe may disclose your information if required to do so by law, or in the good-faith belief that such action is necessary to comply with legal obligations, protect our rights, or protect the safety of users.
4. The @legion AI Feature
When you use the @legion AI feature by mentioning it in a comment or post, the text of your comment is sent to Anthropic's API to generate a response. We do not send your name, email, or other personal identifiers to Anthropic — only the text content of the specific comment. Anthropic's data handling is governed by their own privacy policy, available at anthropic.com/privacy.
5. Data Retention
We retain your personal data for as long as your account is active. If you delete your account, we will delete your profile, posts, comments, and messages within a reasonable period, except where we are required to retain data for legal or safety purposes. Some information (such as moderation records) may be retained in anonymised form for platform integrity purposes.
6. Your Rights
Depending on your jurisdiction, you may have the following rights regarding your personal data:
• Access — request a copy of the personal data we hold about you
• Correction — request that we correct inaccurate data
• Deletion — request that we delete your account and associated data
• Portability — request your data in a portable format
• Objection — object to certain uses of your data
To exercise any of these rights, contact us at
support@joinlegion.app. You can also delete your account directly from Settings → Delete Account.
7. Children's Privacy
Legion is strictly for users aged 18 and over. We do not knowingly collect personal information from anyone under 18. If we become aware that a user under 18 has created an account, we will promptly delete their data and close the account. If you believe a minor has provided us with personal information, please contact us at
support@joinlegion.app.
8. Data Security
We implement appropriate technical and organisational measures to protect your personal data against unauthorised access, alteration, disclosure, or destruction. These include encrypted data transmission (HTTPS/TLS), secure authentication via Supabase, and row-level security policies on our database.
While we take security seriously, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security of your data.
9. International Data Transfers
Legion is a global service. Your data may be stored and processed in countries other than your own, including the United States, where our infrastructure providers operate. By using the App, you consent to the transfer of your data to these countries, which may have different data protection laws than your country of residence.
10. Push Notifications
We may send push notifications to your device to alert you to activity relevant to your account, such as replies to your posts, mentions, or message requests. You can manage notification permissions at any time through your device settings or within the App under Settings → Notifications.
11. Cookies and Similar Technologies
The Legion mobile app does not use browser cookies. We may use local device storage (AsyncStorage) to remember preferences such as your onboarding status and notification settings. This data is stored locally on your device and is not transmitted to our servers.
12. Third-Party Links
The App may contain links to external websites or services, including advertiser websites accessed through sponsored posts. We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies before providing any personal information.
13. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you within the App. The "Last updated" date at the top of this policy will always reflect the most recent revision. Continued use of the App after changes are posted constitutes your acceptance of the updated policy.
