- Effective date: 13 August 2026

1. What these terms are for
Kryptic is a tool that encrypts files. Using it carries one specific risk that ordinary apps do not: encryption that cannot be undone without your passphrase means data loss is possible, and it is permanent. These terms exist mainly to state that plainly before you rely on the app, not to disclaim things nobody expected.
By installing or using Kryptic you accept the terms below. If you do not accept them, do not use the app.
2. There is no way to recover a forgotten passphrase
This is the most important sentence in this document.
Your encryption key is derived from your passphrase on your own device. The passphrase is never stored, never transmitted, and never known to the publisher. There is no master key, no escrow, no recovery code, and no backdoor. Nobody — including the publisher — can decrypt your files without your passphrase.
If you forget your passphrase, the files encrypted with it are permanently unrecoverable. This is the property that makes the encryption worth having. It is not a defect and it cannot be reversed on request.
The same applies to a .kenc file that is damaged, truncated, or partially copied. Kryptic authenticates every block and will refuse to decrypt altered data rather than return something wrong — which is the correct behaviour, and also means a corrupted container cannot be partially salvaged.
3. Keep your originals until you have tested a decryption
Before you delete an original file, decrypt the encrypted copy and confirm you get the original back. Do this the first time you use the app, and after any app update.
This is ordinary advice for any backup or archival tool, and it is the single practice that prevents almost every way this app can cost you data.
4. Open beta
Kryptic is currently released as an open beta. It has an automated test suite, a published container format, and standalone decryption scripts that are checked against real app output — but it has not been through a third-party security audit, and beta software can contain defects that testing did not find.
5. What Kryptic does not protect against
Encryption protects a file's contents against someone who has the file. It does not protect against:
- A compromised device. Malware or someone with access to your unlocked phone can read files before you encrypt them, after you decrypt them, or capture the passphrase as you type it.
- A weak passphrase. A short or guessable passphrase can be attacked offline against the encrypted file. The key derivation makes each guess expensive, but it cannot make a common password strong.
- Metadata. A
.kencfile is identifiable as an encrypted Kryptic container, and its size approximates the size of the original. The original filename is inside the encrypted portion and is not readable without the passphrase, but the existence and approximate size of the file are not hidden. - Someone who can compel your passphrase. Kryptic offers no hidden or deniable volumes.
6. Your responsibilities
- Choose a strong passphrase, and store it somewhere you will still have access to later.
- Keep backups of files that matter, encrypted or not.
- Use the app in compliance with the laws that apply to you. Some jurisdictions restrict the import, export, or use of encryption software; it is your responsibility to know whether that includes yours.
7. Licence
Kryptic is provided to you as a personal, non-exclusive, non-transferable licence to use the application. You may not redistribute a modified build under the Kryptic name.
Kryptic includes open-source components; their licences and attributions are listed in the app under Settings → Open-Source Licences, and in THIRD_PARTY_LICENSES.md.
8. No warranty, and limitation of liability
Kryptic is provided "as is", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement.
To the maximum extent permitted by applicable law, the publisher is not liable for any loss of data, loss of access to data, loss of profits, or any indirect, incidental, special, or consequential damages arising from your use of or inability to use Kryptic — including, specifically, files rendered unreadable by a forgotten passphrase, a corrupted container, or a defect in the software.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain liabilities, so parts of this section may not apply to you. Nothing here limits any liability that cannot lawfully be limited, and nothing here affects your statutory rights as a consumer.
9. Privacy
Kryptic collects no data. See the Privacy Policy.
10. Changes to these terms
Material changes will be reflected here with an updated effective date, and in the app's release notes.
