Plain-language summary: Kinkeep works locally without an account. Cloud sync is optional and tied to a household. We do not sell personal information or use household inventory for targeted advertising.
Information you choose to store
In local mode, inventory, spaces, stock levels, expiry dates, shopping entries, and related activity are stored on your device. Kinkeep does not receive that local-only content.
When you create or join a synced household, Kinkeep processes the household content you choose to sync, including inventory, storage spaces, shopping information, membership, invitations, activity, and sync metadata.
Account information
For signed-in features, we process an account identifier, email address, display information provided by the sign-in provider, household role and membership, device sync identifiers, and entitlement status. Google processes Google sign-in under its own terms and privacy policy.
Barcode lookup
When you scan a barcode, Kinkeep may send the barcode number to Open Food Facts to retrieve product details. Review Open Food Facts' privacy information for its handling of those requests. Product results are editable and may be cached locally.
Website messages
When you submit a support, feedback, privacy, or deletion form, we store the name, email, subject, message, request category, source page, and submission time. To limit abuse, we retain a keyed one-way request fingerprint; we do not store the raw IP address in the contact inbox.
How information is used
- Provide local inventory and shopping features.
- Authenticate accounts and privately synchronize eligible households.
- Administer a household subscription and its five-account limit.
- Answer support, privacy, feedback, and deletion requests.
- Protect Kinkeep and its users from abuse, fraud, and service disruption.
- Maintain, debug, and improve reliability.
Service providers
Kinkeep uses service providers where needed to operate: Supabase for authentication, database, sync, and form processing; Google for Google sign-in; Google Play for Android distribution and purchases; Open Food Facts for optional barcode lookup; and website hosting and domain providers for delivery and operational logs. Each provider processes information under its own terms.
Sharing and sale
We share information with service providers only as needed to operate Kinkeep, comply with law, protect rights and safety, or complete a business transfer subject to appropriate safeguards. We do not sell personal information or share it for cross-context behavioral advertising.
Retention
Local data remains until you remove it, clear app storage, or uninstall the app, subject to device backup behavior. Synced data is retained while the household is active and for a limited period needed for recovery, billing, security, and legal obligations. Support records are retained only as long as reasonably necessary to resolve and document the request. Account deletion removes the hosted account and associated hosted household data according to your role and applicable retention requirements.
Security
We use access controls, encrypted network transport, row-level database policies, and household membership checks intended to protect hosted data. No method of storage or transmission can guarantee absolute security.
Your choices
You can use Kinkeep without an account, choose whether to join a synced household, edit or remove app content, leave a household when allowed, and request account deletion. The in-app deletion control is the fastest route. You may also use our web deletion request.
Children
Kinkeep is a general household utility and is not directed to children under 13. We do not knowingly collect personal information from children under 13 through individual Kinkeep accounts.
Changes
We may update this policy as Kinkeep changes. The effective date above will be revised, and material changes will be communicated where required.
