Terms of Use
By downloading or using CoCrypt, you agree to these terms. CoCrypt is a local, peer-to-peer application. It collects no personal data, requires no account, and transmits nothing to our servers — because we have no servers involved in its operation.
1. Agreement
These Terms of Use constitute a legally binding agreement between you and Beyondend Dev ("we," "us," or "our"), a company registered in Turkey at Zühtüpaşa, Rıfat Bey Sk. No:2 kat:3, 34724 Kadıköy/İstanbul, regarding your use of the CoCrypt application ("the App"). By using the App, you agree to be bound by these Terms. If you do not agree, please do not use the App.
2. The App
CoCrypt is a multi-party file encryption application. It allows a file owner to encrypt any file into a .cvl container using AES-256-GCM, split the encryption key across designated participants using XOR, and distribute each key piece to the corresponding participant encrypted with their EC P-256 public key via ECIES. To decrypt the file, all participants must physically authorise the operation by tapping an NFC tag and completing biometric authentication on their own device. The App operates entirely on your device and over direct NFC connections between participants' devices. Beyondend Dev has no access to your keys, files, or communications.
3. No Account Required
CoCrypt requires no registration, account creation, or login with Beyondend Dev. You use the App without identifying yourself to us. We do not collect, store, or process any personal data. Your cryptographic private key is generated on your device and stored exclusively in Android Keystore or iOS Keychain — inaccessible to us.
4. Intellectual Property
The App, its design, code, name, and associated materials are the intellectual property of Beyondend Dev, protected under applicable copyright and trademark law. You may not copy, modify, distribute, reverse-engineer, or create derivative works from the App without our express written permission.
5. Licence Grant
We grant you a limited, non-exclusive, non-transferable, revocable licence to install and use the App on your personal device(s) for personal, non-commercial purposes, in accordance with these Terms.
6. Acceptable Use
You agree to use the App only for lawful purposes. You must not use the App to store, manage, or facilitate any illegal activity. You are solely responsible for the content you store within the App.
7. No Warranties
The App is provided "as is" without warranty of any kind, express or implied. We make no guarantees regarding the App's availability, reliability, accuracy, or fitness for any particular purpose. Use of the App is at your own risk.
8. Limitation of Liability
To the fullest extent permitted by law, Beyondend Dev shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of, or inability to use, the App — including any loss of data stored within the App. You are solely responsible for maintaining backups of your data.
9. App Store Terms
If you download the App through Apple App Store or Google Play, your use is also governed by the terms of the respective distributor. Beyondend Dev, not the App Store or Google Play, is solely responsible for the App and its content.
10. Modifications
We reserve the right to update or modify these Terms at any time. The updated Terms will be posted within the App or on our website. Continued use of the App after changes constitutes acceptance of the updated Terms.
11. Governing Law
These Terms shall be governed by and construed in accordance with the laws of Turkey. Any disputes arising from these Terms shall be subject to the exclusive jurisdiction of the courts of Turkey.
