Privacy Policy

This Privacy Policy explains how Vault Messaging (“Vault Messaging,” “we,” “us,” or “our”) collects, uses, and protects your information when you use the Vault Messaging mobile app (the “App”). Vault Messaging lets you compose text and audio messages addressed to a recipient’s phone number and a future unlock date; the recipient can open the message only once that date arrives.

By using the App, you agree to the collection and use of information in accordance with this policy.

Information We Collect

Account information

To use the App you sign in with your phone number (verified by SMS), an email address, or an anonymous account. We store the identifier you use to authenticate. If you sign in with a phone number, we store that number so we can deliver messages addressed to you.

Message content

We store the messages you create — including text, audio recordings, images, and video — together with the recipient’s phone number, an optional recipient name you provide, and the unlock date you set. This content is stored so it can be delivered to the intended recipient at the scheduled time.

Contacts

If you choose to select a recipient from your device’s address book, the App requests permission to access your contacts. Your contact list is read on your device to let you pick a recipient. We do not upload your full address book. Only the name and phone number of the recipient you actually select are saved, and only so we can address your message.

Usage and device information

We use Amplitude to collect analytics about how the App is used (for example, which screens are viewed and which actions are taken) and general device information. We use Firebase Crashlytics to collect crash reports and diagnostic data so we can fix problems and improve reliability.

Push notifications

With your permission, we use Firebase Cloud Messaging to send push notifications — for example, to let you know when a message is ready to be opened. We store a device push token for this purpose. You can disable notifications at any time in your device settings.

Purchases

Subscriptions and other purchases are processed by Apple’s App Store or Google Play. We receive confirmation of your purchase and subscription status, but we do not collect or store your payment card details — those are handled by Apple and Google.

How We Use Your Information

• To create, store, schedule, and deliver your time-locked messages.
• To authenticate you and secure your account.
• To send notifications you have opted into.
• To operate, maintain, and improve the App and troubleshoot problems.
• To process and manage purchases and subscriptions.
• To comply with legal obligations and enforce our terms.

How We Share Your Information

We do not sell your personal information. We share information only with the service providers that help us operate the App, and only as needed to provide the service:

• Google Firebase — authentication, database, file storage, notifications, and crash reporting.
• Amplitude — product analytics.
• Apple App Store and Google Play — purchase and subscription processing.
• Your intended recipients — the message you create is made available to the recipient you addressed it to, on or after the unlock date.

We may also disclose information if required to do so by law or in response to valid legal requests.

Data Retention and Deletion

We retain your information for as long as your account is active or as needed to deliver your scheduled messages. You can delete your account and associated data at any time from within the App, or by contacting us. See our Account & Data Deletion page for details.

Security

We use industry-standard measures, including Firebase App Check and access controls, to help protect your information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Children’s Privacy

The App is not directed to children under the age of 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us and we will delete it.

International Users

Your information may be processed and stored on servers located outside your country. By using the App, you consent to the transfer of your information to these locations.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above. Your continued use of the App after changes take effect constitutes acceptance of the updated policy.
