Account & Privacy

This article covers everything related to your CSAPP account — how you sign in, what's stored about you, how to control your data, and how to leave if you decide to.

How sign-in works

CSAPP uses Google Sign-In and Apple Sign-In only. We do not support email/password.

Reasons:

• Security. Federated identity (Google/Apple) is stronger than passwords users typically pick.
• No password reset support tickets. The 30% of support volume that goes to "I forgot my password" doesn't exist.
• Privacy. We never see or store your password.

When you sign in with Google or Apple, CSAPP receives only:

• Your email (used as account identifier)
• Your display name
• Your profile picture (optional)

We do not receive: contacts, calendar, location, or any data you haven't explicitly shared.

What data CSAPP stores

We do not store: payment card details (handled by App Store / Google Play / Stripe), location, IP address logs beyond rate-limiting cache, or any data outside the above.

Privacy controls

Inside the app, Profile → Privacy lets you:

• Toggle whether your likes are public (default: anonymous).
• Toggle whether comments include your display name.
• Delete all chat history with one tap.
• Export your data (JSON file emailed to you within 24 hours).

Account deletion

You can delete your account at any time. Two ways:

Self-service (recommended)

In the app: Profile → Account → Delete account. After confirmation:

• Your followed coins, watchlist, chat history, likes, comments — deleted immediately.
• Your subscription (if active) is cancelled at the end of the current billing period (per platform store policy).
• Email + display name are scrubbed from our systems within 7 days.
• Backups containing your data are purged within 30 days.

Via support

Email [email protected] from the email associated with your account. Subject: "Delete my account." We'll process within one business day.

What persists after deletion

• Subscription transactions are retained by Apple / Google for tax and audit purposes; this is outside CSAPP's control. Subscribe via the platform, cancel via the platform.
• Aggregate analytics (e.g., "X users took the BTC long signal") may persist in anonymized form — your individual contribution is no longer identifiable.

GDPR & KVKK compliance

CSAPP is operated by CSTechnology LLC. We comply with:

• EU GDPR for users in the EU/EEA.
• Turkish KVKK for users in Turkey.
• UK GDPR for users in the UK.

Your rights under these regulations include:

• Right of access — request a copy of your data (Profile → Privacy → Export data).
• Right to rectification — update incorrect data via the app.
• Right to erasure — delete your account (see above).
• Right to data portability — JSON export is portable.
• Right to object — contact support to object to specific processing.

For privacy questions, email [email protected] or see the full Privacy Policy.

Two-factor authentication

We don't have a separate 2FA layer because we rely on Google/Apple's own 2FA. If you have 2FA enabled on your Google or Apple account, signing into CSAPP requires that same 2FA challenge.

If you suspect unauthorized account access:

1. Change your Google/Apple password and rotate 2FA.
2. Sign out of CSAPP on all devices: Profile → Account → Sign out everywhere.
3. Sign back in.

Common mistakes

• Signing up with both Google AND Apple. Each creates a separate CSAPP account because the email may differ. Pick one provider and stick with it.
• Deleting the app without deleting the account. Uninstalling the app doesn't delete data — subscriptions continue auto-renewing, push tokens persist. Delete the account explicitly.
• Cancelling subscription via the app and expecting refunds. Refund policy follows App Store / Google Play standard. Use platform settings for refund requests.
