Calculator Vault

Terms of Use

Effective date: July 9, 2026

These Terms govern your use of Calculator Vault. By downloading or using the app, you agree to these Terms and the applicable Apple terms.

1. Agreement and Eligibility

You may use Calculator Vault only if you can legally enter into this agreement and your use is permitted where you live. If you use the app for an organization, you represent that you are authorized to accept these Terms for that organization. If you do not agree, do not use the app.

2. License and Apple Terms

We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use Calculator Vault on Apple-branded devices you own or control, subject to the App Store Usage Rules. These Terms supplement the Apple Standard Licensed Application End User License Agreement. If these Terms conflict with mandatory Apple terms, the applicable Apple terms control.

3. What the App Provides

Calculator Vault provides a calculator interface and an encrypted, on-device area where you may store selected photos, videos, documents, notes, and password entries. Optional features may include a decoy vault, auto-lock, intruder capture, ads for non-premium users, and premium access controls. Features may vary by app version, device capability, region, and subscription status.

Calculator history and ordinary preferences are local app data but are not part of the AES-encrypted vault. The decoy vault contains a separate demonstration view and should not be treated as a guarantee that another person cannot identify or access the real vault.

4. Your PIN, Security, and Backups

• You are responsible for remembering your PIN, securely saving the 20-digit recovery code generated by the app, and protecting access to your device.
• We cannot see your PIN or recovery code, provide a universal override, or remotely recover encrypted vault content. Your recovery code can reset the PIN locally on the same vault when entered in the calculator.
• You should keep independent copies of important files. Do not use Calculator Vault as the only storage location for irreplaceable content.
• Deleting the app, using Delete All Data, losing both the PIN and recovery code, device damage, software failure, or operating-system changes may make content permanently unavailable.

No cloud backup or recovery service is promised unless a future app version clearly identifies that service as active and confirms successful backup. A setting, animation, or status label alone is not proof that a recoverable backup exists.

5. Photos, Camera, and Local Content

You choose what to import and remain responsible for that content. If you ask the app to remove an original from Photos after import, iOS will present the applicable confirmation flow. Confirm that the encrypted copy opens correctly before deleting an original. Intruder Capture must be enabled by you and may take a front-camera photo after a failed PIN attempt; you are responsible for using this feature lawfully and informing other device users where required.

6. Acceptable Use

You may not use Calculator Vault to:

• store, create, possess, or distribute content that is unlawful or violates another person’s privacy, intellectual-property rights, or other rights;
• harass, exploit, threaten, impersonate, surveil, or harm another person;
• circumvent security, reverse engineer the app except where law expressly permits it, distribute malware, or interfere with the app or its services;
• use camera or intruder-capture functionality where recording is prohibited or without legally required notice or consent; or
• use the app for any fraudulent or illegal activity.

7. Subscriptions and In-App Purchases

If functional premium features are offered, purchases are made through Apple’s In-App Purchase system and are subject to the price, duration, trial, and renewal terms shown in the app and App Store purchase sheet at the time you confirm. A displayed plan or purchase button does not by itself confirm that a transaction has completed or that an entitlement is active.

• Payment is charged to your Apple Account after confirmation.
• An auto-renewable subscription continues for the displayed period until canceled.
• You can manage or cancel a subscription in your Apple Account subscription settings. Cancellation takes effect at the end of the current paid period unless Apple states otherwise.
• Any free trial converts to a paid subscription at the displayed price unless canceled before the trial ends. Unused trial time may be forfeited when a subscription is purchased, where applicable.
• Billing, refunds, payment failures, and family sharing are handled under Apple’s applicable policies.

Prices and availability may vary by region and may change as permitted by Apple’s rules. The Apple purchase sheet is the authoritative confirmation of the amount and renewal period you accept.

8. Privacy

Our Privacy Policy explains on-device processing, Firebase diagnostics, Google Mobile Ads, RevenueCat purchase services, permissions, retention, and privacy choices. By using the app, you acknowledge those practices. Do not email your PIN, recovery code, saved passwords, or vault files to support.

9. App Changes and Availability

We may fix, update, add, limit, or discontinue features to improve security, comply with law, or maintain the app. Remote Config may change operational values such as feature limits, paywall presentation, and legal links, but it does not download executable code. We do not guarantee that every feature will remain available forever or work on every device or iOS version.

10. Ownership

Calculator Vault, including its software, design, text, and branding, is owned by the developer or its licensors and is protected by applicable intellectual-property laws. You retain ownership of content you place in the vault. These Terms do not give us ownership of your vault content.

11. Third-Party Services

The app uses services provided by Apple, Google Firebase, Google Mobile Ads, and RevenueCat. Their services are governed by their own terms and privacy policies. We are not responsible for third-party services outside our reasonable control, but we remain responsible for our selection and use of processors as required by applicable law.

12. Disclaimers

To the maximum extent permitted by law, the app is provided “as is” and “as available,” without warranties of uninterrupted operation, perfect security, fitness for a particular purpose, or recovery of lost data. Encryption lowers risk but cannot eliminate all risks. Nothing in these Terms excludes warranties or consumer rights that cannot legally be excluded.

13. Limitation of Liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, business, or access arising from use of the app. Where liability cannot be excluded, it is limited to the amount you paid for the app or subscription during the 12 months before the claim. Some jurisdictions do not allow these limitations, so they may not apply to you.

14. Termination

You may stop using the app at any time. We may suspend access to online services or terminate this license if you materially violate these Terms, subject to applicable law. Termination does not automatically cancel an App Store subscription; manage cancellation through your Apple Account. Provisions that by their nature should survive termination remain effective.

15. Changes to These Terms

We may update these Terms when features, service providers, or legal requirements change. The effective date will be updated. If a change materially affects your rights, we will provide notice through the app or another appropriate method when required. Continued use after the effective date means you accept the revised Terms to the extent permitted by law.

16. Governing Law

These Terms are governed by the laws applicable where the developer is established, without overriding mandatory consumer protections or dispute rights that apply where you live. Nothing in these Terms limits rights you have under applicable consumer law.
