Summary

Splitease is a group expense splitter for trips. We collect the minimum data needed to make the product work and we do not sell, share, or repurpose anyone's data. There are no user accounts.

What we collect

• Trip data you enter: trip names, member names you add, expense descriptions and amounts, currency selections.
• Anonymous usage analytics via PostHog: page views, button clicks, feature usage. No personal identifiers attached.
• Server logs: IP address, user agent, and request timing for debugging and abuse prevention. Retained for 30 days.

What we do NOT collect

• Email addresses, phone numbers, or any account credentials (we have no signup).
• Payment information.
• Location data.
• Contact lists or device sensors.

Trip data access (link-as-token model)

Splitease has no user identity. The trip URL itself is the auth scope: anyone with the trip URL can read or edit that trip's data. This is the same model as a Google Doc share link. If you want to keep a trip private, do not share the URL.

AI agents and the MCP API

Splitease exposes an MCP (Model Context Protocol) endpoint so AI assistants like ChatGPT and Claude can interact with your trip on your behalf. The same link-as-token rule applies — the AI assistant only sees data for the trip URL you give it. We do not share trip data with AI providers; the assistant fetches it directly from our API using the URL you provided.

Our robots.txt declaresContent-Signal: ai-train=no— meaning we do not consent to having user trip data scraped for AI training.

Third parties

• Vercel — hosting. Receives request data inherent to serving the site.
• Supabase — database. Stores trip data.
• Frankfurter API— currency exchange rates. Receives currency pair codes (e.g. "USD-TWD") when you log expenses in non-base currency. No personal data.
• PostHog — anonymous analytics. Receives page view + click events with a randomized device ID. No name, email, or trip data sent.

Your rights

You can delete a trip at any time from the trip page's settings — this permanently removes all members, expenses, and splits associated with it. There is no separate account to delete because we don't create accounts.
