Chrnox - Privacy Policy

Last updated: 10 August 2026.

Chrnox is a studio for building, exploring, and sharing timelines. This policy explains what data the app collects, why, and the choices you have. We collect as little as possible and never sell your data.

Data we collect

• Account email. If you create an account, your email address is stored by our authentication provider (Supabase) so you can sign in and sync across devices. You can also use the app without an account, in which case your timelines stay only on your device.
• Your content. Timelines you create - titles, events, dates, notes, tags, and any photos you attach - are stored so the app can show them back to you and sync them if you are signed in. Content you choose to publish to the public wall (including your public display name) becomes visible to other users; private photos are stripped before publishing.
• Feedback you submit. When you deliberately send the optional in-app feedback form, its rating and text are sent to PostHog so we can receive and act on your feedback. This one-off delivery does not turn on ongoing usage analytics. Please do not include sensitive information.
• Reports and moderation. If you report a public timeline, we store the report reason, your account id, and identifiers for the reported publication and author. To review the report, we process the reported public content and the author's account/contact details. A bounded summary is delivered to our monitored moderation mailbox through Resend; it can include the reason, account/publication identifiers, author name and email, and excerpts of the reported public timeline.
• Usage analytics (optional, off by default). If you turn analytics on in Settings while signed in, we record account-linked product-interaction and page-view events through PostHog to understand how the app is used. Events use only your opaque account id - never your email address or a separate device identifier. Analytics are not collected while signed out. With analytics off, nothing is sent.

Third parties

• Supabase - hosts your account and synced content (data processor).
• PostHog - receives account-linked usage events if you opt in, plus feedback you deliberately submit through the feedback form (data processor). Automatic interaction capture, session recording, heatmaps, dead-click capture, error/console-log capture, and performance capture are disabled.
• Resend - delivers account/authentication emails and bounded moderation-alert emails to our monitored mailbox (data processor).
• Wikipedia / Wikimedia - when you use the optional enrichment feature, the app requests article summaries and images from Wikipedia. Your request reaches Wikimedia's servers.

We do not use advertising trackers, the iOS Advertising Identifier (IDFA), or App Tracking Transparency. We do not track you across other companies' apps or websites.

Your choices and rights

• Delete your account. You can permanently delete your account and its associated data from inside the app: Settings → Account → Delete account.
• Analytics. Turn it on or off anytime in Settings → Privacy & legal.
• Export. Export your timelines anytime via Settings → Data.
