Privacy Policy
Effective: March 5, 2026 · Operated by DJUMP, MB
Readistry is a private reading log. This policy explains what we collect, what we do not collect, and how to reach us if any of it is wrong.
§ 01 Information We Collect
§ 02 Information We Do Not Collect
- We do not collect payment or credit card information — payments are handled by Apple, Google, or RevenueCat.
- We do not collect or share your reading data with third parties. Your book records are private.
- We do not collect location data, contact lists, or photos.
- We do not sell, rent, or trade your email address. Ever.
§ 03 How We Use Your Information
- To provide the core app — tracking books, sessions, progress, statistics.
- To authenticate your account and sync data across devices.
- To send push notification reminders you have opted into.
- To analyze anonymous app usage patterns and improve the experience.
- Before the app launched, this site offered a one-off launch notice. That form is gone and no new addresses are collected. Addresses given then are still held; write to us to have yours removed.
§ 04 Data Storage and Security
Reading data is stored using Supabase with row-level security (RLS) — only you can read your own records. All traffic is HTTPS. We follow industry-standard security practices and do not share your data with third parties for marketing.
§ 05 Third-Party Services
- Supabase — authentication, database hosting, row-level security.
- PostHog — product analytics, hosted in the EU. Screen views and feature events, linked to your account ID while you are signed in.
- Vercel — cookieless website analytics (page views only).
- Sentry — crash and error diagnostics. No performance tracing is collected.
- Resend — transactional email (the contact form on this site).
- RevenueCat — subscription & payment management (when monetized).
- Apple / Google — OAuth sign-in providers and payment processing.
- Vercel — website hosting (this domain).
§ 06 Your Rights
You may view, update, or delete your data at any time. The app provides account deletion in Settings, which removes all reading records. For other requests — including deleting an address left on the old launch list — write to start@djump.io.
§ 07 Children's Privacy
Readistry is not intended for children under 13 and we do not knowingly collect personal data from them. If you believe a child has provided personal information, please contact us and we will remove it.
§ 08 Changes to This Policy
We may update this policy from time to time. Significant changes will be announced through the app or by updating the effective date at the top of this page.
