+i | What it does

A home for your words.

Record, look back, talk. Four features that stay close to how you feel each day.

01

Conversations that remember

Replies take your past conversations into account. Conversations and what it remembers about you are stored on your device.

02

Voice and text entries

Type, or speak into the microphone. The iPhone version uses Apple’s speech recognition, and audio may be processed on Apple’s servers.

03

Mood marks and looking back

Four marks: quiet day, hard day, hope and precious. Look back by date or mood, search by keyword, or have entries read aloud.

04

An AI connection you choose

By default, replies are put together on your device. Only if you register an AI service URL and API key yourself is conversation content sent to that service to get replies.

This page is based mainly on the current iPhone version. Features and settings depend on your OS and app version.

+i | Privacy and download

Clear about how your words are handled.

Because this app keeps your conversations, we tell you clearly where they are stored and when the app communicates.

Everyday conversations and memories

By default, replies are put together on your device and conversations and memories are stored there. Our servers do not receive them.

Encryption on iPhone

Conversation text is encrypted on the device with AES-256, with the key kept in the Keychain, as stated in the app’s description.

When you use voice input

The iPhone version uses Apple’s speech recognition. Audio may be processed on Apple’s servers.

If you choose to connect an AI

Only if you register a URL and API key is conversation content sent to the service you specified. Clear the setting to stop it.

About ads

An AdMob ad is shown at the top of the screen, and the app communicates with Google to deliver ads. Conversation content is never passed to advertisers.

Deletion and age rating

The iPhone version can delete all data on the device at once. Store age ratings: Apple 4+, Google Play 3+.
