Frequently Asked Security Questions

Where is my data stored?

All data is stored on EU servers (Supabase Postgres). Encrypted transmission via TLS 1.3, fully GDPR compliant.

What does Zero Drift mean for calculations?

Zero Drift means: 0 cent deviation in calculations. Every transaction is deterministically computed and fully traceable — even with 10,000+ transactions.

Can FairSplit access my financial data?

No. Row Level Security (RLS) at the database level ensures that only group members can access their data. No data sharing with third parties.

Does FairSplit work securely offline?

Yes. Local data is stored encrypted in IndexedDB. Idempotent sync mechanisms prevent duplicates, retry queues ensure data integrity during connection loss.
