Piggy privacy policy
Last updated: July 2026
Piggy is a personal expense-tracking app. This page explains what data it collects, what it's used for, and what rights you have over it.
What data is collected
- Account: your email address, managed by our authentication provider (Clerk). We never see or store your password.
- Financial data you enter yourself: transactions (amount, concept, date, category), categories, trips, budgets, annual and recurring expenses. This is the data you type in while using the app — nothing is imported from any bank or external service.
- Subscription, only if you buy the paid plan: an internal identifier for your account and your subscription status (whether it's active and until when). Billing is handled by Google Play: we never see or store your card or any payment data.
No location, contacts, photos, or any data you haven't entered yourself are collected.
What it's used for
Exclusively to run the app: showing you your transactions, computing your summaries and dashboards, and generating the Excel export you request. It's never used for advertising, and no profiles are built.
Who it's shared with
- Clerk (authentication): manages your login.
- Railway (hosting): hosts the database and the app's server.
- RevenueCat (subscriptions, only if you buy the paid plan): checks with Google Play that your purchase is valid and tells us its status. It receives an internal identifier for your account and that subscription's history; it never receives your transactions or any financial data of yours.
- Google Play (billing, only if you buy the paid plan): processes the payment and manages the subscription. Your payment data is theirs and never passes through us.
We never sell or share your data with third parties for advertising. There are no third-party trackers or analytics inside the app.
Security
Connections between the app and the server are encrypted (HTTPS). If you turn on fingerprint or face lock, your phone's operating system handles the biometrics — it never leaves your device or reaches our servers. We keep encrypted database backups with a maximum retention of 30 days, used only for disaster recovery.
How long your data is kept
For as long as your account exists. If you delete your account, all your data is erased immediately and permanently (unless it was already part of an earlier encrypted backup, which expires on its own within 30 days at most).
Your rights
- Access and rectification: you can view and edit all your data directly inside the app at any time.
- Portability: you can export your data to Excel from More → Export.
- Deletion: you can delete your account and all your data from More → Delete account, or by following the instructions on this page.
Minors
Piggy is not directed at minors.
