Privacy Policy - BlindVaultEffective date: July 7, 2026
Developer: ZelTools - https://zeltools.comTHE SHORT VERSION
BlindVault is an offline password generator. Your passwords are generated locally on your device using cryptographically secure randomness, are never stored by the app, and never leave your device. BlindVault has no user accounts and we do not collect, store, or sell any personal data.1. DATA THE APP STORES - LOCALLY ON YOUR DEVICE ONLY
BlindVault stores a small amount of data only on your device, solely so the app can function:
• Generator presets (e.g. "Banking: 20 characters, no symbols") - saved in a local database. Presets contain only generation settings, never generated passwords.
• App preferences - your theme choice and a cached copy of your Premium status.
This data never leaves your device, is not transmitted to us or anyone else, and is permanently deleted when you uninstall the app.2. DATA WE NEVER COLLECT
• Generated passwords or passphrases (they are never written to storage by the app)
• Names, email addresses, or any account information (there are no accounts)
• Contacts, location, files, photos, or any other personal content3. THIRD-PARTY SERVICES
Google Play Billing - used to process the optional one-time Premium purchase. Payment is handled entirely by Google Play; we never receive your payment card details. See the Google Privacy Policy at https://policies.google.com/privacy.Google AdMob (free version only) - the free version of BlindVault shows banner advertisements served by Google AdMob. AdMob may collect and process data such as your device's advertising ID, IP address, and general device information to serve and measure ads. Learn more in the Google Privacy Policy (https://policies.google.com/privacy) and "How Google uses data from partner apps" (https://policies.google.com/technologies/partner-sites). You can reset or delete your advertising ID in your device's Google settings. Purchasing Premium removes all ads and, with them, all ad-related data processing.4. APP PERMISSIONS EXPLAINED
• Internet & network state - used exclusively for showing ads (free version) and communicating with Google Play Billing. Password generation itself is 100% offline and works in airplane mode.
• Advertising ID - used by Google AdMob to serve ads in the free version.
• Notifications (optional) - used for helpful local notifications, such as a clipboard hygiene reminder after copying a password from the home screen widget. You can deny this permission; the app works fully without it.5. SECURITY
Passwords are generated with your device's cryptographically secure random number generator and exist only on screen and, if you choose to copy them, temporarily in your clipboard. On Android 13+, copied passwords are flagged as sensitive so they are masked in the clipboard preview. We recommend pasting your password promptly and then copying something else to clear it.6. CHILDREN
BlindVault is not directed at children under 13 and collects no personal data from any user.7. YOUR CHOICES
• Remove all advertising by purchasing Premium (one-time).
• Deny the notification permission at any time in system settings.
• Delete all locally stored data instantly by uninstalling the app.8. CHANGES TO THIS POLICY
If we change this policy, the updated version will be published at this address with a new effective date. Material changes will be highlighted in the app's update notes.9. CONTACT

Terms & Conditions - BlindVaultEffective date: July 7, 2026
Developer: ZelTools - https://zeltools.com1. Acceptance of these terms
By downloading, installing, or using BlindVault ("the App"), you agree to these Terms & Conditions. If you do not agree, please do not use the App.2. What BlindVault does
BlindVault is an offline utility that generates random passwords and passphrases locally on your device. The App intentionally does not store, back up, or transmit generated passwords. Once a password leaves your screen or clipboard, the App has no record of it and cannot recover it.3. License
ZelTools grants you a personal, non-exclusive, non-transferable, revocable license to use the App on Android devices you own or control, subject to the Google Play Terms of Service. You may not copy, modify, distribute, sell, reverse-engineer, or lease any part of the App except where such restriction is prohibited by law.4. Free version and advertising
The free version of the App displays banner advertisements served by Google AdMob and limits certain generator parameters (for example, password length up to 12 characters).5. Premium (one-time purchase)
• BlindVault Premium is a one-time in-app purchase, not a subscription. The price is shown in the App before purchase.
• Premium unlocks extended password lengths (up to 64 characters), precise parameter controls, the home screen widget, Dark Mode, and removes all advertising.
• Payment is processed by Google Play. Refunds are governed by the Google Play refund policy.
• Premium is linked to your Google account and can be restored on any device with the "Restore Purchases" button after installing the App and signing in with the same Google account.6. Your responsibility for passwords
You are solely responsible for storing and safeguarding any password you generate. Because the App never saves generated passwords, ZelTools cannot recover a lost password under any circumstances. The App's crack-time estimates are statistical approximations provided for guidance only; no password can be guaranteed uncrackable, and password strength alone does not protect against phishing, data breaches at third-party services, or malware on your device.7. Disclaimer of warranty
The App is provided "as is" and "as available" without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement. ZelTools does not warrant that the App will be uninterrupted or error-free.8. Limitation of liability
To the maximum extent permitted by applicable law, ZelTools shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, accounts, or profits, arising out of or related to your use of the App. In any case, total liability shall not exceed the amount you paid for the App in the twelve months preceding the claim.9. Intellectual property
The App, including its design, logo, branding, and code, is the property of ZelTools and is protected by applicable intellectual property laws.10. Changes to the App and these terms
We may update the App and these terms from time to time. The current version of these terms will always be available at this address. Continued use of the App after changes take effect constitutes acceptance of the revised terms.11. Termination
This license terminates automatically if you breach these terms. You may terminate it at any time by uninstalling the App.12. Governing law
These terms are governed by the laws of the Netherlands, without regard to conflict-of-law principles.13. Contact
