Bijdehand (atHand) is the family information app from NovaEdge. We do not sell your data or share it for advertising. You and the people given access by an authorised parent can use the shared family information.
This policy covers Android / iOS, app identifier nl.novaedge.bijdehand.
Who we are and how to contact us
NovaEdge is responsible for the processing described here. For privacy questions or requests, contact privacy@novaedge.nl. For help using the app, contact info@novaedge.nl.
What information is processed
Your email address, account ID and authentication information are used for your account. You choose which family details to enter, such as names, contact details, photos, notes, schools, care contacts and recurring days. This may include information about children or sensitive information. Only enter information you need and are allowed to use and share.
Why we process information
We use account and technical information to provide sign-in, synchronisation, access control, recovery, deletion and security. The app does not automatically read your phone contacts or request GPS location. It has no advertising or analytics SDK. Google Play and Apple may separately process technical and beta-testing information under their own policies.
Encrypted family information
Family content and photos are encrypted on your device before synchronisation. The cloud stores encrypted content; private keys are not sent to our server during normal operation. Local family data and pending changes are encrypted too. Email addresses, account IDs, memberships, public keys, revisions, timestamps and encrypted packet sizes remain technical metadata visible to the service. Connections use HTTPS.
Our service provider
Supabase processes authentication information, encrypted family vaults and technical metadata on our behalf. We do not share family information with advertising companies.
Parents, children and guests
Connected parents share the family vault as equal co-owners within the app. They jointly agree which parents retain each child record after separation; changing that agreement requires all current parents to approve. Personal parent records remain with that parent. This app arrangement does not establish legal ownership of personal data or parental authority.
Child access and guest access are separate read-only selections without the family key. An authorised parent chooses the shared details and can revoke access. Guest access can have an end date, and one guest can help several independent families. When opening or resuming the guest view, the app first checks access online; old shared content is cleared or replaced before display. Without that check, guest content is not shown.
Offline use and recovery
Parents can use their loaded family vault offline and synchronise later. Keep your personal recovery card in a private place outside your phone. Recovery on a new device needs your login and card, or help from an authorised co-parent. A password reset does not restore an encryption key. Without a card, trusted device or authorised co-parent, we cannot recover encrypted family content. Signing out locks the vault but does not erase the local copy.
Deleting your account or information
Use Account and storage in the app. Deleting your own account automatically removes your Bijdehand account and personal parent record. With other parents connected, the agreed child-record distribution is applied first; they retain their access and assigned records. Their approval is not needed to delete your own account. Deleting the entire shared cloud vault is a separate choice requiring every current parent to confirm. Erasing only this device leaves your account and cloud vault in place.
What may remain after deletion
Minimal technical deletion markers prevent old identities from restoring deleted access. Necessary public verification keys and encrypted transfer proofs may remain for other parents. An authentication login also used by another app can remain for that app, while Bijdehand access and recovery state are removed. A fixed automatic deletion period for historical administrative backups has not yet been implemented.
Your privacy questions and requests
Contact privacy@novaedge.nl about access, correction, deletion or other rights concerning your personal data. We verify that a request comes from the account holder. Depending on applicable law, you can also contact your local data protection authority. We cannot read or recover family content for which we do not hold decryption keys.
Children and care information
Parents and carers manage the family information. Child access does not make a child profile public. The app does not diagnose conditions or provide medical advice.
Changes and current limits
This policy describes the current app, including guest access and self-service account deletion. Retention arrangements and independent security review are still being developed. We update this policy when processing changes.
