Split Peak

Privacy Policy

Last updated: July 20, 2026

Split Peak ("we", "the app") helps groups split and settle shared expenses. We built it to collect as little as possible: there are no accounts, no sign-up, no ads, and no tracking. This policy explains what data the app handles and why.

Information we handle

• Group content you enter — the group and member names, expenses, amounts, notes, categories, currencies, and any payment-app handles (e.g. Venmo, PayPal) you choose to add. This is what makes the app work: computing splits and settlements.
• Receipt photos — only if you use receipt scanning. When you photograph or upload a receipt, the image is sent to our AI provider to read its line items, and the photo is stored with the expense so the group can check it later. We ask the provider not to return card numbers, cardholder names, or addresses, and we discard anything of that kind before saving. See Retention below for how long photos are kept.
• Device notification token — only if you turn on push notifications, we store a device token so we can send you alerts (for example, when someone adds an expense to your group).
• Basic technical data — standard server logs and anonymous error reports used to keep the service running. We do not attach your name or contact details to these.

We do not collect your contacts, location, browsing history, or advertising identifiers, and we do not ask for an email address or password to use the app.

How we use it

Data is used solely to provide the app's features — storing your groups, calculating who owes whom, converting currencies, and delivering notifications you've opted into. We do not use your data for advertising, we do not sell it, and we do not track you across other apps or websites.

Service providers

We rely on a few processors to run the app, who handle data only on our behalf:

• Hosting — our servers and database (Railway).
• Push notifications — Firebase Cloud Messaging (Google), if you enable them.
• Error monitoring — Sentry, configured to exclude personal data.
• Exchange rates — a public rates API is queried for currency conversion (no personal data is sent).
• Receipt reading — Google (Gemini API), only when you scan a receipt. We use a paid tier, under which Google does not use your content to train its models.

Sharing

Group content is visible to anyone who has your group's join code or link — that's how group members see the same data. We don't share your data with anyone else except the service providers above.

Retention & deletion

Group data is kept until the group is deleted. Anyone in a group can delete it at any time from the group's Settings, which permanently removes that group's data from our servers. To turn off notifications, disable them in your device settings.

Receipt photos are kept for 12 months, then automatically deleted. Deleting the expense or the group removes the photo straight away. The line items and amounts read from a receipt are part of your group's expense history and are kept for as long as the group is.

We keep encrypted backups so we can recover from a failure. Data you delete may persist in these backups for up to 3 months before it is permanently removed.

Security

All traffic is encrypted in transit (HTTPS). No system is perfectly secure, but we keep data collection minimal to limit exposure.

Children

Split Peak is not directed to children under 13, and we do not knowingly collect their information.

Changes

If we update this policy, we'll revise the date above and post the new version at this URL.
