Terms of Use

Using CalcLock

These terms govern the CalcLock app and calclock.app website, provided by Click Media Group Pty Ltd. Using either means you accept these terms. If you disagree, stop using them. App Store downloads are also covered by Apple’s Standard End User Licence Agreement and purchase terms.

What the app does

CalcLock is a working calculator with encrypted photo and file vaults. Each vault opens with its exact equation, not the equation’s answer. Encryption combines the equation with a device-held secret. Files and filenames are encrypted on your device using AES-256-GCM.

We do not hold your vault files, equations or decryption keys on our servers. There is no provider-managed account reset or automatic cloud sync. Support emails are separate from your vaults: never send equations, backup passwords or private files.

What you are responsible for

• Your equations: remember the exact expression for each vault and keep it private.
• Your device: protect it and its stored data. Loss, reset or uninstalling can permanently remove access.
• Your files: keep independent copies of irreplaceable content. Check imports and backups before deleting originals.
• Your use: store only content you have the right to use, and do not use CalcLock for unlawful activity.

Lost access and recovery

We cannot reset a forgotten equation, bypass encryption or recover inaccessible files. Version 1 has no portable backup or export. A normal device or iCloud backup must not be assumed to restore working vault access.

Versions with portable backups let you export an individual vault into an encrypted file protected by a separate backup password. You must create and keep that file yourself. An intact backup and its password can restore the vault under a new equation in a compatible version. Without them, forgetting the equation may mean permanent loss. We cannot recover a forgotten backup password. This feature is not automatic sync or a whole-app backup.

Paid features

• Available plans, features and prices appear in the app before purchase. They may differ by version and region.
• Apple processes in-app payments. Subscription renewal follows the purchase confirmation; deleting the app does not cancel billing.
• Manage or cancel subscriptions in your Apple account settings. Cancellation stops future renewal under Apple’s terms; it does not itself reverse a payment already made. Use Apple’s purchase-support process for refund requests. We do not control Apple’s refund decisions.
• Restore purchases using the Apple account used to buy them. A refund, revocation or subscription expiry can end access to the associated paid features; it does not recover or decrypt a vault.
• A purchase does not include unannounced future features.

Decoy vaults and deletion

You can create a vault of unimportant content with its own equation and choose to show that vault. Opening it does not list or erase your other vaults. CalcLock does not currently offer shared-vault access or an automatic duress-delete feature.

Deleting files, destroying a vault or resetting all vaults removes the affected local copies without undo. Originals and backups outside the app are not deleted. Deletion does not guarantee forensic erasure. A disguise or decoy cannot guarantee protection against discovery or coercion.

Ownership and permission to use

Your files remain yours. CalcLock’s code, design, branding and website material belong to us or their respective rights holders. You may use the app on devices you own or are authorised to use under its App Store licence. You may not resell or sublicense it, distribute unauthorised copies, remove ownership notices, imply our endorsement, bypass purchase checks or interfere with the app or website. You must not use them to infringe privacy or intellectual-property rights, harass others or distribute harmful content. You are responsible for content you import, export or share. Apple’s licence governs restrictions on modification and reverse engineering; open-source components retain their own licences.

No warranty. Use at your own risk.

CalcLock and this website are supplied as is, without warranty. You use them at your own risk. We disclaim express and implied warranties of quality, fitness for a particular purpose, accuracy and non-infringement. We do not guarantee continuous availability, error-free operation, support for every file or device, or that defects will be fixed. Encryption does not make any system infallible. Support advice or other communications do not create an additional warranty.

Risk of loss and liability

To the maximum extent permitted by law, the warranty exclusions, waivers and liability limits in these terms apply. You accept the risk of files being lost, damaged, corrupted, disclosed or inaccessible, including through forgotten equations, lost passwords, lockouts, device failure, software errors or deletion. You waive claims against Click Media Group Pty Ltd arising from that loss or inability to access your files.

We exclude liability for indirect, incidental, special, consequential or punitive losses, including lost profits, business interruption and lost business opportunities. These limitations apply to claims arising from the app, website or inability to use them, whether based on contract, negligence or another legal basis, even if the possibility of loss was brought to our attention.

Our total liability for all claims arising from CalcLock or this website is limited to the greater of US$50 and the total amount you paid for CalcLock during the 12 months before the event giving rise to the claim. Related events count as one event for this limit.

Third-party services and ending use

Apple, device software, file providers and other external services are outside our control. Their availability, errors, storage decisions and terms can affect use of CalcLock. You are responsible for copies you send to another app or service.

You may stop using CalcLock at any time. Secure any independent copies you need before removing the app. We may terminate permission to use the app or website for a material breach of these terms. This does not give us remote access to your vaults or a way to delete them. Ending use does not cancel an Apple subscription, erase an existing payment obligation or remove provisions concerning ownership, loss, liability or claims.

Updates to these terms

We may update these terms at any time. The updated terms apply from the time they appear on this page. By continuing to use CalcLock after an update is posted, you accept the revised terms. The date above shows when they were last updated.

If one provision is unenforceable, the remaining provisions continue to apply. Not enforcing a provision on one occasion does not waive our right to enforce it later. These terms and the applicable App Store licence govern your use; neither transfers ownership of your content to us.
