Privacy Policy

Last updated: August 5, 2026

Coinly ("we", "the app") is a personal expense and income tracker for Android. This page explains what data the app handles and how.

Coinly has no servers. We do not run a backend, we do not have a database of users, and we never receive a copy of your financial data. Everything below is about data that stays on your device or goes directly to services you already own.

Data stored on your device

All of your wallets, transactions, categories, budgets, and any receipt photos you attach are stored locally on your device using a local database. This data never leaves your device unless you explicitly enable backup — and receipt photos never leave it at all, since a backup contains only your wallets, categories, transactions and budgets, never the images themselves.

Using Coinly without an account

Signing in is optional. You can install Coinly and use every tracking feature — wallets, transactions, categories, budgets, recurring entries, reports — without creating an account or giving us anything at all. An account is only needed for the two features that genuinely require an identity: Google Drive backup, and carrying a Coinly Pro purchase across devices.

Google Drive backup (optional)

• Backup is off by default and only activates if you sign in and enable it.
• Backups are written to your own Google Drive account, inside a private, hidden application-data folder that only Coinly can access — not your visible Drive files.
• We request the narrowest Google Drive scope available (drive.appdata), which cannot see or touch any other file in your Drive.
• Coinly has no servers of its own — we never receive or store a copy of your backup.

Sign-in

If you choose to sign in with Google, we use Google's Credential Manager to authenticate you. Your name, email address, and profile photo are stored on your device so the app can show who is signed in. We only use this to identify your account for backup and restore — we do not use it for advertising and we do not share it with third parties.

Purchases

If Coinly Pro is purchased, payment is handled entirely by Google Play. Coinly never sees, collects, or stores your card or payment details.

• We use RevenueCat to check whether a purchase is active. It receives a purchase identifier and, if you are signed in, an anonymous per-account identifier derived from your Google account — not your email address.
• This is used only to unlock features you have paid for and to restore them on another device. It is not used for advertising or profiling.
• Google Play keeps its own billing records under Google's privacy policy, which we do not control.

Deleting your account and data

You can delete your account and everything associated with it — device data and your Google Drive backup — from inside the app at any time, under More → Delete Account. Full instructions, including what happens to subscriptions and how to proceed if you have already uninstalled the app, are on our account deletion page.

Exchange rates

To convert your wallets into your Base Currency, Coinly fetches published exchange rates from open.er-api.com once a day and caches them on your device. The request asks for rates and nothing else — it carries no account, no identifier, and none of your financial data.

Analytics & advertising

Coinly contains no third-party advertising SDKs and no analytics or tracking SDKs. We do not profile you, and we do not sell or share data with data brokers. If that ever changes, this policy will be updated before it does.

Children

Coinly is not directed at children under 13 and we do not knowingly collect data from them.
