Bookflow

Privacy Policy

Effective date: May 23, 2026  ·  Last updated: May 23, 2026

This Privacy Policy describes how Bookflow ("Bookflow", "we", "us", or "our") collects, uses, shares, and protects information when you use the Bookflow mobile application (the "App") and our website at getbookflow.co (together, the "Service").

By using the Service you agree to the practices described here. If you don't agree, please don't use the Service.

1. Who we are

Bookflow is an independent reading-companion app operated by an individual developer based in Lagos, Nigeria. You can reach us anytime at support@getbookflow.co.

2. Information we collect

2.1 Information you give us

2.2 Information collected automatically

2.3 Information we do not collect

3. How we use information

4. Sub-processors and third parties

We use the following service providers ("sub-processors") to operate the Service. We share only the data each one needs to do its job, and each is bound by their own privacy commitments.

ProviderPurposeData shared
Supabase Authentication, database, file storage, realtime sync, serverless functions Account info, your library, avatar, app events that need to persist
Anthropic (Claude) AI features: summaries, chat, recommendations Text you submit for AI processing (e.g. a passage you ask about)
ElevenLabs Text-to-speech narration Text segments you request to be read aloud
RevenueCat Subscription management and entitlement checks An anonymous app-user ID and your subscription state
PostHog Product analytics (pseudonymous) Usage events tied to a random install ID, not your email
Sentry Crash and error reporting Stack traces, device model, app version
Resend Transactional email delivery (magic links, receipts) Your email address and the email body
Apple App Store / Google Play Billing Purchase processing Whatever Apple or Google needs for the transaction; we never see your card details

We do not sell your personal information. We do not share it with advertisers.

5. Legal basis (for users in the EEA / UK)

If you are in the European Economic Area or the United Kingdom, our legal basis for processing your personal information is:

6. Data retention

7. Your rights

Depending on where you live, you may have the right to:

To exercise any of these, email support@getbookflow.co. We respond within 30 days.

8. How to delete your account

You can delete your account and the personal data tied to it in two ways:

  1. In the app — open the You tab → AccountDelete account. You'll be asked to confirm. Deletion happens immediately and is irreversible.
  2. By email — send a request from your account email to support@getbookflow.co with the subject "Delete my account". We will verify and process the deletion within 7 days.

When you delete your account, we delete: your profile, your library, highlights and notes, avatar, and authentication records. Pseudonymous analytics events and encrypted backups may persist for up to 90 days before they are purged on their normal schedule. We do not retain anything that can re-identify you after that window.

9. Children's privacy

Bookflow is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, contact support@getbookflow.co and we will delete it.

10. International data transfers

Some of our sub-processors are based outside your country. Where required, we rely on Standard Contractual Clauses or equivalent transfer mechanisms to protect your data.

11. Security

We use industry-standard safeguards including TLS in transit, encryption at rest, scoped API tokens, row-level security on user data, and least-privilege access controls. No system is perfectly secure; if you believe your account has been compromised, contact support@getbookflow.co immediately.

12. Changes to this policy

We may update this Privacy Policy. When we make material changes we will update the "Last updated" date at the top and, where appropriate, notify you in-app or by email. Continued use of the Service after a change means you accept the updated policy.
