🐹 HamsterFi Privacy Policy

Last updated: June 20, 2026

HamsterFi is an envelope-budgeting app for households, built by 288 Labs, LLC. This policy explains what we collect, why, and your rights. Questions: privacy@288labs.com.

1. What we collect

No account required

You can set up and use a full budget with no account at all. Your budget is created under an anonymous session and stored securely on our servers (tied to this device until you sign in); we do not collect your name, email, or any identity to use the app.

Optional account (for syncing)

If you choose to sign in to back up and sync across devices, we collect what the provider gives us:

• Sign in with Apple — your name and email from Apple. You may choose to hide your email (Apple provides a private relay address instead).
• Google Sign-In (Android) — your Google account ID, name, and email.

We do not use email-and-password accounts, and we never see or store a password.

Budget data

• Household name, jars (envelopes), allocations, transactions, recurring payments, and budget settings you create
• Your chosen display name and animal icon

Device & diagnostics

• App version, OS version, device model
• Anonymized product-usage events (which screens/features are used)

2. How we use your data

• Run the product (save your budget, sync across devices if you sign in, send household invitations)
• Improve the product (anonymized analytics)

We do not sell your data. We do not show third-party ads. We do not use any third-party AI service, and we do not use your content to train any AI model.

3. What we do not collect

We do not connect to your bank or any financial institution. We never see, store, or share banking credentials, balances, or transactions beyond what you manually enter. We do not access your microphone, contacts, photos, or location. No advertising IDs, no cross-app tracking.

4. Sub-processors

• Supabase — authentication and database storage. Region: US. Encrypted in transit (TLS) and at rest.
• RevenueCat — subscription status only (no card numbers; Apple handles payment).
• PostHog — product analytics. Region: US. Events are anonymized: we do not send jar names, transaction notes, your name, or your email.
• Apple — App Store, in-app purchases, and Sign in with Apple.
• Google — Google Sign-In (Android only).

5. Sharing

Members of your household can see all budget data attached to that household. We share data with no one else except as required by law.

6. Retention

• Budget and account data — kept until you delete your account, then removed from our database.
• Analytics events — retained up to 12 months, then aggregated.

7. Your rights

You can permanently delete your account and all associated data in the app: Household → Delete Account. Deletion is immediate and unrecoverable. You can also request access, correction, or export by emailing privacy@288labs.com (we action requests within 30 days). EU/UK/EEA residents have rights under GDPR; California residents under CCPA. We honor both globally.

8. Children

HamsterFi is not directed at children under 13 (16 in some EU jurisdictions). We do not knowingly collect data from children under 13.

9. Security

All data is encrypted in transit (TLS) and at rest. Access inside 288 Labs is restricted to a small number of authorized people.

10. Changes

We will post changes here and update the "Last updated" date. Material changes are also announced in-app.
