TAHIN Privacy Policy
Effective 1 November 2026. TAHIN is an expense and split manager. Contact support@tahin.in.
Information we process
We process your email and sign-in identity, profile/member name, country and currency preferences, groups, invitations, expenses, notes, splits, and settlements to provide the app. Optional profile images are stored locally; a device-local image path may be saved with your profile. Expense data is also cached locally for offline use.
Firebase, provided by Google, supplies authentication, Firestore, Cloud Functions and Cloud Messaging. Resend delivers email verification codes. These service providers process information needed to provide those services, including operational/security logs. Device activity records, push tokens, IP addresses and request counters support notifications, security and abuse prevention. App Check may process device attestation signals.
Sharing and choices
Group information, member names and shared financial records are visible to other members of the group. Invitation codes grant access to a member slot: share them only with the intended person. CSV exports are shared only when you choose to export using your device sharing tools. We do not sell your personal financial records. Camera access is used to scan invitation QR codes. Photo and file access is used only for features you choose. Notifications are optional and controlled through app/device settings. Biometric checks use your device security; TAHIN does not receive your fingerprint, face template or device PIN.
Importing from Tricount
When you choose a Tricount sharing link, TAHIN contacts Tricount over HTTPS using a temporary anonymous session to read that shared group. You can review the preview before importing. Selected member names, expenses, shares and repayments are copied into your TAHIN group and follow the same local storage, cloud synchronization and group sharing rules as other TAHIN records. Receipts are not copied. TAHIN does not change Tricount, retain your sharing link or session token, or continuously synchronize with it.
Advertising and privacy choices
TAHIN displays Google AdMob advertisements. The Google Mobile Ads SDK may process IP addresses, device and advertising identifiers, app and ad interactions, and performance or diagnostic information to deliver and measure ads and prevent fraud. IP addresses may be used to estimate general location. Data processing depends on your device, privacy choices and the SDK configuration.
We do not send your name, email, group contents, expense amounts, receipts, notes, splits, settlements or balances to AdMob for ad targeting. Where required, an in-app consent message and advertising privacy options let you review or change your choices. Device settings also provide advertising privacy controls. Your choices can affect whether ads are personalized, limited or unavailable. Read how Google uses information from apps that use its services and Google's privacy policy.
Security and retention
Cloud connections use encryption in transit. Access controls restrict cloud data to authorized users; local records remain in app storage. We retain account and expense data while needed to provide the service. Verification codes expire after five minutes; expired records and abuse counters are scheduled for cleanup. Expired invitations cannot be claimed.
Account deletion
Use Settings → Delete account in the app, or follow the account deletion request instructions. Deletion removes your authentication account, private profile, device records, notification tokens and verification records. Groups with no other joined account are deleted. For shared groups, administration passes to a remaining member and your member slot and associated identifying ledger fields are anonymized as “Deleted member” so other members can retain their expense history and balances. Shared monetary records remain. A minimal technical deletion marker is retained to prevent old authentication tokens restoring access. Data exported by other members is outside our control.
Contact and updates
For access, correction, deletion or privacy questions, email support@tahin.in. Service providers may process data outside your country. We will update this page when our practices change.
