Everything you need to know about how mammoth-app keeps your conversations private and secure.
Every message you send is encrypted on your device before it leaves, using industry-standard end-to-end encryption. Only the intended recipient can decrypt and read it. Our servers never have access to your plaintext messages, ensuring your conversations remain completely private.
Chat deletion is intentionally disabled to maintain message integrity and a tamper-proof conversation history. This ensures that no party can alter or erase the record of a conversation, providing accountability and a reliable, timestamped archive of all communications.
Single-device access is enforced as an additional layer of security. By tying your account to one device, we minimize the risk of unauthorized access from compromised or shared devices, keeping your encrypted vault as secure as possible.
Yes, mammoth-app is fully GDPR compliant. We collect only the minimum data necessary to operate the service, and all stored information is protected with encryption. You have full rights to access, review, and request removal of your personal data at any time.
Your account password is encrypted using strong hashing algorithms and is never stored in plaintext. If you forget your password, you can initiate a secure recovery process via your registered email. For security reasons, we cannot retrieve your original password — a new one must be created.
We store only the essentials: your encrypted messages with timestamps, your hashed account password, and basic profile information. We do not store multimedia, voice data, or images because mammoth-app is a text-only platform by design. All stored data is encrypted at rest.
Join mammoth-app and take control of your conversations. Encrypted, simple, and built for your privacy.
