Data Storage

Last updated: January 2026 · Plain English explanation of where your data lives

Your data is stored securely in the United States, isolated from other clubs, encrypted in transit, and backed up daily. You can export or delete it at any time.

Where is my data stored?

All StringPro data is stored in Supabase, a managed PostgreSQL database service hosted on AWS (Amazon Web Services) infrastructure in the United States (US East region).

Is my data isolated from other clubs?

Yes. Every database query is filtered by your unique club ID using row-level security at the database level. It is technically impossible for one club to read another club's data.

Is my data encrypted?

In transit: All data between your device and our servers is encrypted using TLS 1.2+
At rest: Supabase encrypts all data at rest using AES-256
Passwords and PINs: Never stored in plain text — always hashed using bcrypt

How long is my data kept?

Active accounts: indefinitely
Cancelled accounts: 90 days after cancellation, then permanently deleted
Deleted clients or jobs: removed immediately from the app, purged from database within 24 hours

Is my data backed up?

Supabase performs automatic daily backups with point-in-time recovery. In the event of data loss we can restore to any point within the last 7 days.

Can I export my data?

Yes. Go to Jobs → Export CSV to download all your job records at any time. This is your data — you can take it with you whenever you want.

Can I delete my data?

Yes. Email privacy@stringpro.org to request complete account and data deletion. We will process deletion within 5 business days and send you confirmation.

Who at StringPro can access my data?

Only authorised StringPro engineers can access the database for support and maintenance purposes. All access is logged. We do not browse customer data unless required to diagnose a specific support issue you have raised.
