Features

Everything Mann does, and what it deliberately doesn’t.

Four things, built well, rather than thirty built adequately. Below that: the things we decided not to build at all, and why.

Privacy

Encrypted before it leaves your phone.

Every entry is sealed with AES-256-GCM on your device, before any network request. The key is a random 256-bit key generated the first time you use Mann and held in your phone’s secure hardware (iOS Keychain or Android Keystore). We never receive it, so we have no way to read your entries, and no way to recover them for you.

It’s a private diary with lock in the everyday sense too: turn on the biometric lock and Mann asks for your fingerprint or face before it opens.

Two honest exceptionsWhen you finish an entry, its full text goes to Google Gemini for a private safety check, to write your reflection, and to note anything you left unresolved. Tapping Go Deeper mid-entry sends your text the same way, for a safety check and to write the next question. On Premium, viewing a finished entry Mann has already reflected on sends its full text one further time, to write a longer second reflection and label the entry with a theme; that happens on the screen you land on right after saving as well as on any later visit, once per entry. And if the safety check finds a crisis signal, your full text is sent once more, to write the helpline message itself. All of that is processed in flight, never retained. Chat conversations aren’t encrypted yet, though: Mann needs to read them to remember what you told it, so they are stored as plain text. Encrypting chat is on our roadmap, and this page will keep saying so until it ships.

What you write

Aaj bahut frustrated tha work se. Manager ne phir dismiss kar diya.

Encrypted on your device
What gets stored

The stored version is unreadable ciphertext.

AES-256-GCM, with a key generated on your phone and held in the device keychain. We never receive it, so we have no way to read your entries or move them for you.

Languages

Journal in the language you actually think in.

Mann writes back in 8 Indian languages. The app itself is in Hindi, Hinglish and English, with more coming.

Most apps translate. If you’ve set your language to Hinglish, Mann was tuned to answer in kind: a sentence that starts in English and turns Hindi halfway through gets a reply the same way, not flattened into formal Hindi nobody speaks.

3 interface languages today, with more coming. Replying and the app’s own screens are two different things, and we don’t mix them up here.

Long-term memory

Mann remembers, so you don’t have to repeat yourself.

While your reflection is being written, Mann quietly notes a short list of things you left open (a meeting you’re dreading, an answer you’re still waiting on). These are meant to be things you actually said, not a conclusion about you, and a filter checks each line for that before it’s saved.

It holds at most ten of these at a time, drops anything resolved, and lets go of anything you haven’t mentioned again within 30 days. Read every line, or delete any of them, at Profile → “What Mann remembers”.

The proactive check-ins that bring one of these back up on their own are a premium feature. The memory itself, and your ability to see and delete it, is free on every plan.

Insights

A weekly report on the week you just had.

Every Sunday evening, Mann writes a short report from real patterns: what the mood tracker saw across the week, how many days you wrote, daily word counts, and a Cast of Characters built from names you mention more than once.

The report itself is generated for every account, and free accounts see a locked preview of it. Premium unlocks the full report, plus recurring themes pulled from a deeper second pass Mann only runs for premium accounts.

By omission

Four things Mann will never do.

A product is defined as much by what it refuses to build.

No manipulative streaks

No red badge, no guilt notification, no “you’re about to lose your streak” push at 11pm. Miss a couple of days and the streak just quietly ends.

No advertisers

Your data is never sold, rented or traded. There’s nothing to sell: most of it is ciphertext. The whole business model is a ₹199/month subscription, and that’s it.

No training on your words

Nothing you write trains a model, not ours, not Google’s: that’s a condition of the paid API we use, not a promise our own code enforces alone. The full text of an entry is processed in flight to write a reflection, and it’s not retained afterward.

No pretending to be a therapist

Mann asks questions. It doesn’t diagnose, prescribe, or claim clinical outcomes. If a crisis signal is detected, you get real helplines instead of a reflection.

Three minutes to your first entry.

Free, forever, for the basics. No card, no trial countdown, no email sequence.
