MemX is not end-to-end encrypted. Here is why we say so.
Questions
Is MemX safe?
MemX is private by architecture. Each memory is encrypted with a key unique to your account, data is encrypted at rest, and every decrypt is audit-logged. The service decrypts data only when you use the app, for example to answer a question.
Is MemX end-to-end encrypted?
No. MemX is private by architecture. Each memory is encrypted with a key unique to your account, and the service decrypts data only when you use the app, for example to answer a question. Every read is logged.
Who can read my memories?
MemX reads them only when you open a memory, search, ask, or save a file for MemX to read. MemX is private by architecture: a separate key per account, encrypted at rest, and every decryption logged by Google Cloud.
Can I see an audit log?
Every decrypt is logged by Google Cloud. Where the audit log is available in your app, the Encryption screen lets you generate a log of access to your data from the last 30 days and download it. Links expire seven days after creation.
What is stored on my phone?
Your chat history and cached memories are stored in encrypted local databases with per-user keys. You can also lock the app with Face ID, Touch ID, fingerprint or a PIN.
Does MemX train AI on my data?
No. Your data is processed by MemX and the AI partners it names (Google, OpenAI, xAI and Anthropic) to answer you and organise your files. Those partners are contractually barred from training on it.
