This document contains both the Privacy Policy and Terms of Service for EZCrypt ("we", "us", or "our"), an offline-first, end-to-end encrypted messaging and encryption tool on Android, iOS, or other supported platforms. By downloading, installing, or using the App, you agree to the practices and terms described below.
Developer / Publisher: SO SEN
1. Information We Do Not Collect
EZCrypt is architected around absolute local privacy. Messages, notes, contacts, and cryptographic keys remain exclusively on your device:
- Message and note content is not stored or read by us. All plain text is encrypted locally using AES-256-GCM and ECC P-256 hybrid cryptography before transmission or storage.
- Your private encryption keys never leave your device and are never backed up to our servers.
- Contact records, public keys, and cryptographic pairings are stored locally in secure on-device storage.
- We do not require account registration, telephone numbers, or email sign-ins.
2. Advertising & Third-Party SDKs (Google AdMob)
EZCrypt is monetized by displaying advertisements served by Google AdMob to help keep the utility free to use. AdMob and its bidding mediation partners may automatically collect and process certain non-personal device diagnostics, including:
- Mobile Advertising ID (Google GAID or iOS IDFA).
- Device identifiers, operating system build, and application version.
- IP address, general network metrics, and approximate geolocation.
- Ad interaction and performance telemetry for frequency management and fraud prevention.
This information is processed directly by Google under the Google Privacy Policy.
Consent & User Messaging Platform (UMP)
Where required by applicable regulations (such as in the European Economic Area and the United Kingdom), we implement Google's User Messaging Platform (UMP) to gather explicit user consent before serving ads. You can manage or revoke personalized advertising preferences at any time through your device settings.
3. Terms of Service
By using EZCrypt, you expressly understand and agree to the following conditions:
- User Cryptographic Responsibility: EZCrypt is an offline, client-side encryption utility. Because we do not possess master keys or escrow recovery mechanisms, you are solely responsible for maintaining backups of your private keys and passwords. If you lose your private key or forget your decryption credentials, your encrypted data cannot be recovered by us.
- Lawful Use Only: You agree to use EZCrypt strictly for lawful communications and data protection purposes. You must not use the application to facilitate illegal operations, distribute harmful software, or evade valid legal obligations.
- Advertising Consent: EZCrypt is provided free of charge supported by advertising. Using the application constitutes consent to the delivery of third-party advertisements via Google AdMob and certified networks.
- Intellectual Property: All software architecture, interface designs, cryptographic integration logic, and branding belong exclusively to SO SEN. Reverse engineering, decompiling, or distributing unauthorized clones of the application package is prohibited.
4. Data Retention & Security
Encrypted messages, notes, and local keys reside on your device until manually deleted or cleared via device application cache. Communications with third-party advertising SDKs are secured using industry-standard TLS/HTTPS encryption protocols. While we implement rigorous client-side cryptographic standards, no computing environment is unconditionally immune to device-level compromise.
5. Children's Privacy
The App is not directed to children under 13 (or the minimum legal age in your territory). We do not knowingly collect personal identifiable data from children.
6. Changes to Policy & Terms
We may update this documentation periodically. Continued use of EZCrypt following any modifications signifies your acceptance of the updated terms.
