Terms of Service

1. Agreement

These Terms govern your use of the Kistvault application ("Kistvault", "the app") provided by [operator legal name] ("we", "us"). By downloading, installing, or using Kistvault, you agree to these Terms. If you do not agree, do not use the app. Your use is also subject to the app store's terms (Apple Media Services Terms or Google Play Terms of Service) and our Privacy Policy.

2. License

We grant you a personal, non-exclusive, non-transferable, revocable license to use Kistvault on devices you own or control, in accordance with these Terms and the applicable app store terms. You may not copy (except as the app store permits), modify, reverse engineer, decompile, or create derivative works of the app except to the extent this restriction is prohibited by applicable law.

3. How Kistvault works — and the key thing you must understand

Kistvault is an on-device, zero-knowledge encrypted vault. Your files are encrypted and stored only on your device. We operate no server for Kistvault and have no access to your files, your password or pattern, or your encryption keys.

You are solely responsible for remembering your password or pattern and for safely keeping your Recovery Kit and any exports you create. Because the encryption is designed so that only you can open your vault:

If you lose every way to unlock your vault — your password or pattern, and your Recovery Kit — your data cannot be recovered by anyone, including us. There is no backdoor, no master key, and no reset.

You acknowledge and accept this as a deliberate security property of the app.

4. Your responsibilities

• Choose a strong password or pattern and keep it confidential.
• Create and safely store your Recovery Kit; keep any encrypted exports somewhere you control.
• Maintain your own device backups as appropriate. Kistvault's content is excluded from ordinary device cloud backups by design; recovery comes from your Recovery Kit or your own export, not from an iCloud or Google restore.
• Use Kistvault only for lawful purposes and only with content you have the right to store.
• Keep your device and its operating system secure. Protections offered by Kistvault depend on the security of the device and operating system, which we do not control.

5. What Kistvault does and does not protect

Kistvault's security protections are described in plain language in the app (the Protection Report) and are stated honestly. In particular, you acknowledge that:

• On iPhone, the operating system provides no way to block screenshots or screen recording; Kistvault can only detect a screenshot after it happens. On Android, Kistvault blocks screenshots and screen recording of vault content.
• No application can prevent someone from photographing the screen with another camera.
• No application can guarantee that deleted data is securely erased from flash storage.
• Kistvault is a general-purpose privacy tool. It is not marketed as, and must not be relied upon as, protection against sophisticated or state-level adversaries.

6. No accounts; no fees for access to your content

Kistvault requires no account. If a future version offers paid features, you will always retain the ability to open, view, and export content you have already stored, regardless of any paid status.

7. Updates

We may provide updates to Kistvault. Some updates may be required for continued operation or to maintain compatibility with the operating system or app store requirements. We may change or discontinue features; where a change would affect how your data is handled, we will reflect it in the app and in the Privacy Policy.

8. Disclaimer of warranties

To the maximum extent permitted by law, Kistvault is provided "as is" and "as available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that it will prevent all unauthorized access to your device or data. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you, and you may have statutory rights that these Terms do not affect.

9. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data or loss of access to data, arising out of or relating to your use of (or inability to use) Kistvault — including, without limitation, loss resulting from a forgotten password or pattern, a lost Recovery Kit, device loss or failure, or failure to maintain your own backups. Our total aggregate liability for any claim relating to the app will not exceed the amount you paid for the app (if any) in the twelve months before the claim. Nothing in these Terms excludes liability that cannot be excluded under applicable law.

10. Termination

These Terms apply until terminated. They terminate automatically if you breach them. On termination, you must stop using the app and delete it. Sections that by their nature should survive (including Sections 3, 8, 9, and 11) survive termination.

11. Governing law

These Terms are governed by the laws of [jurisdiction], without regard to its conflict-of-laws rules, except where mandatory consumer-protection law in your country of residence applies.

Apple note: the licensed application is licensed, not sold, to you. If you obtained Kistvault from the Apple App Store, Apple's standard Licensed Application End User License Agreement terms also apply (including Apple being a third-party beneficiary entitled to enforce these Terms), to the extent you rely on Apple's default EULA rather than this custom one.
