Vault - Terms and Conditions
Calc Vault Terms of Use
Effective date: 30 October 2026 · App: Calc Vault: Hide Photos & Apps (com.dev.calculator.vault)
These terms apply to your use of Calc Vault ("the app"), made by Saffron Applications ("we", "us"). By installing or using the app you agree to them. If you do not agree, please uninstall the app. How we handle information is explained in our Privacy Policy.
1. What the app does
Calc Vault looks and works like a calculator. Entering your PIN opens a private vault where you can hide photos, videos, audio and documents, and use features such as App Lock, Lock WhatsApp chats, Hide apps, Hide notifications, private notes, hidden contacts, a private browser, Intruder selfie and optional Google Drive backup. Some features need permissions that you grant in Android settings; the app explains each one before asking, and you can turn them off at any time.
2. Your PIN and recovery
- You are responsible for choosing a PIN and keeping it secret.
- Set up a recovery method (fingerprint or security question) in Settings. Without one, a forgotten PIN may mean you cannot open the vault.
- We do not store your PIN or your files on any server, so we cannot reset your PIN or recover your files.
3. Your files
- Hidden files are moved into a private folder on your phone so other apps such as the gallery do not show them. They stay on your device.
- Uninstalling the app, clearing its data, resetting your phone, a damaged storage card or removing files with another file manager or a computer can permanently delete hidden files. Unhide or back up anything important first.
- Google Drive backup is optional. When you turn it on, files are copied to your own Google Drive account and Google's terms apply to that storage.
- You are responsible for the content you hide and must have the right to store it.
4. Acceptable use
Use the app only on a device you own or are allowed to manage, and only for lawful purposes. Do not use it to hide illegal content, to monitor or lock another person's phone without their permission, or to copy, modify, reverse engineer or resell the app.
5. Ads and purchases
- The app is free and shows ads provided by Google AdMob.
- An optional one-time "Remove ads" purchase is sold through Google Play. Payment, refunds and billing are handled by Google Play under its terms. The purchase is linked to your Google account and can be restored from Settings.
6. Third-party services
The app uses services from Google (Google Play, AdMob, Firebase and Google Drive). Your use of those services is also subject to Google's own terms and policies. We are not responsible for third-party services or websites opened from the app, including pages you visit in the private browser.
7. No guarantee
The app is provided "as is" and "as available". We work to keep it reliable, but we do not promise that it will be error-free, always available, or able to stop every attempt to access your phone (for example by someone who knows your phone's own lock, or on a rooted or modified device). Android or other apps may change in ways that affect features such as App Lock.
8. Limitation of liability
To the fullest extent allowed by law, Saffron Applications is not liable for any loss of data, files or profits, or for any indirect or consequential damages arising from your use of, or inability to use, the app. Nothing in these terms limits any rights you have under consumer laws that cannot be excluded.
9. Ending use
You can stop using the app at any time by uninstalling it (unhide or back up your files first). We may suspend or stop offering the app, or any feature, at any time.
10. Changes to these terms
We may update these terms. The new version will be posted on this page with a new effective date. Continuing to use the app after a change means you accept the updated terms.
