Emopi

PRIVACY & SECURITY

How your words
are protected

The words Emopi holds are deeply personal. So this page explains, without hedging, which words reach someone and which words no one else can read.

SHARING

Only as much as you choose.

Being able to write freely is where everything starts. The journal stays your own place, and only what you want to pass on reaches the other person, in a gentle form.

Your journal

The text never reaches the person you connect with.

What reaches them

It looks like work has been tiring for a while. Taking time to listen today might help them feel at ease.

Only how they are doing, and a gentle hint.

The text never reaches them

Your journal entries and your exchanges with AI are never shared with the person you connect with through Emopi.

You decide the scope

Mood, energy, care hint — you choose which items to show, item by item, and can change it at any time.

AI shapes it to land gently

What reaches them is not the detail, but how you are doing and something they can quietly do. Secrets stay secret.

ENCRYPTION

Protected by two encryption schemes

Emopi uses a different scheme for the journal and for talk. Journal entries use application-level encryption; talk uses end-to-end (E2E) encryption once the E2E keys are ready. Messages sent before that, and legacy messages, are encrypted at rest at the application level.

Journal

Application-level encryption

Journal text is encrypted by the application before it is stored on the server. It is decrypted only to provide features such as summaries and mood analysis; we do not routinely read the text.

Can read
You, and AI (only while providing a feature)
Cannot read
The person you connect with (only shared items reach them)

Talk

E2E encryption (once keys are ready)

Once a connection’s E2E keys are available on supported devices, talk messages are encrypted on the device before they are sent. The keys needed to decrypt them live on your device and theirs, and the ciphertext and wrapped keys stored on our servers are not enough to recover the text. Messages sent before the E2E keys are ready, and legacy messages, are stored encrypted with AES-256-GCM on the server and can be decrypted by our systems where necessary to operate the service.

E2E
Only your supported devices and theirs
Before keys / legacy
Decryptable by our systems where necessary to operate the service

In talk, the only thing AI sees is the draft you choose to show it for advice before sending.

When you change or add a device, the design allows an existing supported device to hand the encrypted keys to the new one.

E2E encryption uses a shared key per connection; there is no per-message forward secrecy. Device public keys follow a trust-on-first-use (TOFU) model against a directory our servers manage.

What we protect,
in the journal and in talk

No message text in notifications

Push notifications carry only fixed phrases such as “a new message has arrived”. The content of the words never appears on the lock screen.

All traffic encrypted

Traffic between the app and the server is always encrypted (TLS).

Change the scope at any time

Among mood, energy, and the care hint, you can reselect what the other person sees at any time. Journal text and your exchanges with AI are never shared.

Deletion is in your hands

You can delete your account and data from the app at any time. See the account deletion page for the steps.

What we want to be honest about

  • Even with device-to-device encryption, usage information such as send and receive timestamps and message counts is handled on the server to operate the service.
  • AI processes journal text only to provide features such as summaries and mood analysis, and to check for safety. We do not use the text for any other purpose.
  • The legal details, including how we respond to disclosure requests under applicable law, are set out in the Privacy Policy.

For the legal details, see ourPrivacy Policy.
