Your thoughts are yours. Cryptographically.
Most AI assistants read everything you type. Reminda is different: all your notes, memories, and flashcards are encrypted on your device before they ever reach our servers. We physically cannot read your data — even if we wanted to.
The Hard Truth
AI usage history is
more dangerous than you think.
Imagine everything you have ever shared with AI — private thoughts, confidential code, and personal data — leaked to the public one day.
Myth
Reality
My conversations are strictly between me and a chatbot.
Human engineers can review your logs for "quality training" anytime.
Let's protect your data
Reminda's E2EE solution
Client-Side AES-256-GCM Protocol
User Request
Initiate secure handshake
Processing
Encrypt with session key
Reminda server
Encrypted data stored safely
Delivery
Encrypted transmission
User device
Decrypt to plain text
Technical architecture
Zero-knowledge by design, not by policy
Most privacy claims are policies. Ours is mathematics. You cannot decrypt data without the key — and only your device holds it.
Reminda encryption stack
Your password becomes a device-side key — slow enough to prevent brute-force
Military-grade authenticated encryption with integrity verification
Keys are never persisted to disk or transmitted over the network
Our servers receive, store, and transmit only ciphertext blobs
Only the context your current session requires is temporarily decrypted
What we can see
Your key, your data
The encryption key exists only in your device's memory during an active session. When you close the app, the key is erased. We have no key escrow, no backdoor, and no administrative override.
Threat model
What attacks we protect against
Server breach
Encrypted blobs are meaningless without the client-side key. A database leak reveals nothing readable.
Man-in-the-middle
TLS 1.3 + client-side encryption ensures intercepted traffic is double-protected ciphertext.
Insider threat
Even Reminda engineers cannot access user content. Zero plaintext storage by design.
Government subpoena
We can only hand over ciphertext. We physically cannot produce your plaintext data.
AI model training
Your data is encrypted before reaching any AI provider. Model APIs see only session-scoped temporary decryptions.
Third-party leaks
No analytics SDKs, no ad networks, and no data brokers have access to your encrypted information.
Privacy that matters — for every use case
Executive strategy notes, M&A research, board memos — protected from corporate espionage and data broker exposure.
Pre-publication lab findings, patent data, and manuscript drafts remain encrypted until you choose to share.
Personal study notes, academic performance data, and exam strategies stay private between you and your device.
API keys, architecture decisions, and proprietary algorithms stored in encrypted code snippet decks.
Security & privacy FAQ
Can Reminda employees read my notes?
No. The architecture makes this technically impossible. Only encrypted ciphertext is stored server-side. Without your client-side key, we cannot decrypt anything.
What happens if I forget my password?
Because we use zero-knowledge encryption, we cannot recover your data without your password. We recommend using a secure password manager and enabling backup codes.
Does E2EE slow down the app?
Encryption and decryption happen in milliseconds using native browser WebCrypto APIs. In practice, users cannot perceive any performance difference.
Is Reminda open source?
Our encryption libraries and client-side cryptographic implementation are open for independent audit. Contact security@reminda.ai for access to our security documentation.
How is this different from other private AI tools?
Most 'private AI' tools promise not to look at your data — a policy. Our architecture makes it mathematically impossible to read your data — that's a cryptographic guarantee.
Think freely. We can't read it anyway.
