Privacy & ads

Last updated: July 28, 2026

The short version: your splits live in your own browser. Receipt photos are sent to our server only to be read by AI, and we don't sell your data. Advertising may support the cost of keeping the app free.

What we process, and where it lives

Receipt photos. When you scan a receipt, the photo is sent to our server and passed to an AI provider (such as Anthropic Claude or Google Gemini) to extract the line items. Photos are processed to answer that one request and are not kept on our server afterwards.
Your splits. Items, names, and amounts are stored locally in your browser (localStorage). Clearing your browser data removes them.
Optional account sync. If you sign in, your splits are also stored in our database (Google Firebase) so they can follow you across devices. This is entirely optional — the app works without an account.
Share links. When you share a split, the data needed to display it is encoded in the link or stored so that recipients can open it. Only share links with people you want to see the split.

Advertising (Google AdSense)

We use, or may use after site approval, Google AdSense on pages with publisher-authored content. We do not intentionally place ads on receipt entry, item assignment, settlement, account, alert, error, or share-only screens. When AdSense is active, Google may serve and measure ads as follows:

Third-party vendors, including Google, use cookies and similar technologies to serve ads based on your prior visits to this and other websites.
Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet. You can read how Google uses data from partner sites at policies.google.com/technologies/partner-sites.
You can opt out of personalized advertising at Google Ads Settings or via aboutads.info.
If you're in a region that requires it (for example the EEA, UK, or Switzerland), you'll be asked for consent before personalized ads are shown.

Cookies & local storage

StingySplitter itself uses browser storage to keep your splits, settings, and (if you sign in) your session on your device. When advertising is active, advertising cookies may be set by Google as described above; we don't run our own analytics or tracking cookies.

Deleting your data

Local splits can be removed from the app's settings or by clearing your browser data. If you signed in and want your synced data deleted, email us and we'll remove it.
