Encryption

Welfare cases, incident reports, medical notes and API keys are stored encrypted.

Two-step sign-in

Optional authenticator-app verification for every staff account.

Audit log

Who changed what and when — receipts, approvals, exports and logins.

Backups & export

Daily database backups with checksums; export all your data as CSV files any time.

Yes. Every screen is responsive and it can be installed on a phone like an app. Members get their own portal for receipts, ID card, bookings and help requests.
