Terms & Conditions

Last updated 10 November 2026

These terms govern your use of Guardikey. By downloading, installing, or subscribing, you agree to them. Please read them, together with our Privacy Policy and Refund Policy.

1. Who you are contracting with

Guardikey is provided by Apexium Technology, a registered sole proprietorship based in Antalya, Türkiye (“we”, “us”, the “Provider”). You can reach us at [email protected].

2. Your licence

Subject to these terms and your active plan, we grant you a personal, non-exclusive, non-transferable licence to install and use Guardikey on the number of devices your plan allows (Free: one device; Pro: up to five devices for one person; Family: up to five people and twenty-five devices). You may not resell, sublicense, reverse engineer except as permitted by law, or remove any security or attribution from the software.

3. Your master password and recovery

Guardikey is zero-knowledge: your data is encrypted with a key derived from your master password, which never leaves your device. We cannot recover or reset your master password, and we cannot recover your vault if you lose it. You are responsible for remembering your master password and for keeping your recovery kit safe. This is a deliberate security property, not a limitation we can override.

4. Subscriptions, renewal, and cancellation

Paid plans are billed monthly or yearly through Paddle and renew automatically until cancelled. You can cancel at any time through the management link in your purchase emails or by contacting Paddle; cancellation stops future renewals and your paid features remain active until the end of the current period. Prices and taxes shown at checkout are final for that purchase.

5. Refunds

We offer a 30-day money-back guarantee on your first charge, handled by Paddle as Merchant of Record. See our Refund Policy for details and how to request one.

6. Acceptable use

You agree to use Guardikey lawfully and not to use it to store or transmit unlawful content, to breach others’ rights, to attempt to disrupt or compromise the service, or to circumvent device or plan limits. We may suspend accounts that abuse the service or put others at risk.

7. The crypto wallet is self-custody

Guardikey includes a self-custody crypto wallet. Your seed phrase and keys are generated and stored encrypted on your device only; we never hold them and cannot access your funds or reverse a transaction. You are solely responsible for your keys, your seed backup, and any transactions you make. Guardikey does not provide financial, investment, or tax advice, and nothing in the product is such advice.

8. Disclaimers

Guardikey is provided “as is” and “as available”. While we work hard on its security and reliability, to the maximum extent permitted by law we do not warrant that it will be uninterrupted, error-free, or fit for a particular purpose. You remain responsible for maintaining your own backups of important data.

9. Limitation of liability

To the maximum extent permitted by law, our total liability arising out of or relating to Guardikey is limited to the amount you paid for it in the twelve months before the event giving rise to the claim. We are not liable for indirect or consequential losses, or for loss of data resulting from a forgotten master password or lost recovery kit. Nothing in these terms limits liability that cannot be limited by law.

10. Changes

We may update the service and these terms. Material changes take effect when posted here, shown by the “last updated” date. Continued use after a change means you accept the updated terms.

11. Governing law

These terms are governed by the laws of the Republic of Türkiye, without prejudice to mandatory consumer-protection rights you may have where you live.

12. Contact

Apexium Technology — [email protected]. For billing, invoices, and refunds, contact Paddle as our Merchant of Record.
