Privacy Policy.
BLKH01E was built so that privacy is the starting point, not an afterthought. This policy explains, in plain language, how the product is designed around your data.

Template for review. This document is a working draft and should be reviewed and finalized by qualified legal counsel before launch. Contact addresses are placeholders.
Our approach
BLKH01E is designed around a local-first architecture. Your private vault contents (files, photos, messages, passwords, audio and notes) are encrypted on your device. The core architecture does not rely on a central server that stores the contents of your private vault, and there is no master password stored on our servers.
Information we do not collect
- We do not maintain a central database of your private vault contents.
- We do not store your master password or the keys that protect your vault.
- We do not sell personal information.
Information that may be processed
Depending on the features you use and how the app is distributed, limited information may be processed:
- App Store & subscriptions. Purchases and subscriptions are handled by Apple. We do not receive your payment card details. Apple may share limited transaction information needed to provide and validate your subscription.
- Encrypted communication. When you use messaging, message content is end-to-end encrypted. Transport services may still observe certain metadata such as network addresses or connection timing, depending on the transport architecture.
- Diagnostics. Any diagnostics are designed to be minimized and are not intended to identify the contents of your vault.
Metadata & third parties
No system operates in isolation. Networks, operating systems and third-party services may observe certain information depending on how they are used. BLKH01E is designed to minimize exposure, not to claim that nothing can ever be observed.
Data retention & deletion
Encrypted content lives on your device and in any backups you choose to create. BLKH01E uses cryptographic deletion: when the key protecting an item is destroyed, the encrypted content can no longer be decrypted through that key. This is key destruction, not a guarantee of physical overwrite of storage media.
Your controls
- You control your credentials, your keys and what you store.
- You can create and export your own backups.
- You can manage or cancel subscriptions through your Apple account settings.
Children
BLKH01E is not directed to children, and we do not knowingly collect information from children.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected here with an updated date.
