Datum / Privacy
Your content.
Your choices.
Datum encrypts and decrypts text locally. Opewell does not operate an account, messaging server, analytics service, or message history for the app.
On your device
Datum does not save plaintext drafts, message history or message passphrases. Containers and their metadata are stored in a device-local, non-synchronizing Keychain item protected by device authentication. A device passcode is required; removing it may invalidate stored containers. Keep protected backups.
Sharing, clipboard and backups
Copying is explicit. Clipboard content is local-only and expires after 60 seconds; other apps may access or retain copies. Datum shares encrypted output. Protected container exports use a separate export password and are encrypted before a temporary sharing file is written. Your chosen sharing destination or file provider may retain, synchronize or process files under its own practices.
Lost container copies or passphrases can make messages unrecoverable. Opewell cannot restore them. Deleting local content or clearing the app does not delete external copies. Backgrounding covers sensitive UI and clears active state, but cannot guarantee erasure of all system memory, screenshots or external copies.
Purchases
Apple StoreKit handles product information, payment and entitlement verification for the one-time Datum Pro purchase. All container operations require Pro; existing containers remain stored when entitlement is unavailable, but access requires Pro. Opewell does not receive payment-card details. Apple may process purchase and diagnostic information according to its own settings and policies; see Apple’s privacy information.
Children and sensitive information
Datum is a general-purpose tool, not a service designed to collect children’s information. Take care when entering or sharing sensitive information. If a child has sent personal information to Opewell through support, contact us to request its removal.
Support and privacy requests
Opewell is the independent publisher responsible for this notice. Contact [email protected] with privacy questions or requests about information you have sent us.
If you contact us, we receive your email address, message, and any attachments you choose to include. We use this information to respond, troubleshoot, and maintain relevant support records. Our support mailbox uses Gmail, so Google and your email provider also process correspondence. Please do not send passwords, private documents, or vault files.
Retention and your choices
We retain support correspondence while needed to address the request, maintain relevant records, or meet applicable legal obligations. Retention depends on the purpose and any unresolved issue; this notice does not promise an automatic deletion date. You may ask us to access, correct, or delete information you have provided. We may need to verify the request and retain information where required by law.
We cannot access or delete content held only on your device or in backups you control. Manage that content through the app, iOS settings, and the storage providers you use. Depending on where you live, additional privacy rights or the right to complain to your local data-protection authority may apply.
Service providers and disclosure
We use service providers to operate the website and handle email. They may process information in countries other than yours under their own applicable terms and safeguards. We may disclose information we hold when required by law or necessary to protect people, investigate abuse, or secure our services. The website and apps do not include advertising networks or tools for selling your app content.
Changes to this notice
We will update this page and its date when relevant practices change. Material changes will be explained through the website or app as appropriate. This notice describes the app features and website practices covered above.
Website privacy covers website hosting and contact behavior separately. See Datum support for security and recovery guidance.
