Privacy

Philosopher In My Pocket ("the app", "we") is run by Satyartha Saxena, in India. You can write to us at satyartha.work@gmail.com.

People write the most private things they own into this app. So our rule is simple: anything we do not need to keep, we do not keep. This page says exactly what happens to what you write, in plain words. If anything here is unclear, write to us and a person will answer.

The short version

Your conversations stay on your phone. We do not keep a copy of what you write or of the answers you get, unless you choose to send one to us, for example when you report an answer. Your book, your saved ideas and any half-written question are stored only on your phone.
Before your words are sent to the AI, our server tries to remove identifying details such as names and contact details. It cannot guarantee that every detail is caught, for example an unusual name or a workplace. You can always use first names only or leave names out; the advice works just as well.
The AI is never told who you are. Your cleaned words are sent to the AI by our server, not by your phone. Nothing about you is sent with them: no name, no email, no account, no phone code and no internet address. To the AI, every question from every person comes from one sender, which is this app.
We never write your words into our logs. Our logs only count things, such as how many answers were given today.
We measure how the app is used, without knowing who you are. The totals carry no name, no email, no device code and no internet address.
No ads, no outside analytics or tracking companies, and we never sell your data.
If you write about wanting to harm yourself, your message is not sent to the AI at all. You see real helplines straight away.

What happens when you ask a question

Your message goes to our server.
The server tries to remove identifying details (see above).
The cleaned message is sent to Google's Gemini AI, which writes the answer.
The answer comes back to your phone and is saved there, in your book.

The app uses Google's paid Gemini service. Under Google's terms for that service, Google does not use your messages to train its AI or to improve its products. Like any service of this kind, Google may keep messages for a limited time only to check for misuse. Our server still removes the names and contact details it can spot before anything is sent.

Does Google know which person is asking? No. Google receives the cleaned message from our server under the app's own account, the same account for everyone. We do not send Google your name, your email address, your account with us, your phone's code or your internet address, and Google has no way to tell that two questions came from the same person. The only thing that could still point to you is a detail you write yourself that our cleaning does not catch, for example an unusual name or the place you work. If you leave such details out, the AI is answering a person it knows nothing about.

When you ask a follow-up, earlier parts of the same conversation are sent with it, cleaned the same way, so the reply stays connected. We do not store them either.

If you speak instead of typing, your phone's own voice typing (from Google or Apple) turns your voice into words before our server ever sees it. That part is between you and your phone's maker.

If you tap Listen, the answer is sent to our voice provider to be read aloud. What you wrote is never sent to them, only the answer.

How we measure use of the app

To improve the app, we keep anonymous totals of how it is used, for example how many answers were read to the end on a given day, or how many people used Listen. Your phone sends small labelled counts, and our server adds them into totals per day and per country.

Never included: your words, your name or email, a device code or account, your internet address, your city or the exact time. Where something you wrote is counted at all, only its rough length is used.
Also counted: whether a visit came from the iPhone app, the Android app or the web. If you opened the app from a link we posted somewhere, for example on a forum, the link's short label is counted too, so we know which of our posts people came from; the label is about our post, not about you. And if the app itself fails on your phone, we count that it happened and which version of the app it was, never the error text or anything you wrote.
Why there is no switch: because the totals contain nothing about you, turning them off would protect nothing.
How long: the daily totals are deleted after 25 months.

What we keep on our server

A random code for your phone, containing no name, email or phone number, used to apply the fair-use limit and to allow one free trial per phone. It is never linked to the usage totals.
Short-lived usage counts for that code, used only for the fair-use limit and deleted automatically once they are no longer needed.
Your account details, described under Signing in below.
The anonymous usage totals described above.

Messages you send us

When you use "Tell us what you think" or "Report this answer", we keep your message so we can read it. We remove the phone numbers, email addresses and other contact details we can spot. A report includes the answer only if you tick the box, and the answer may mention what you wrote. We keep your email only if you tick "You may reply to me by email". Messages are deleted after 180 days. Write to us to have one deleted sooner.

Your free trial

You sign in with Google to use the app, and that opens a 30-day free trial, with no card needed. Help for anyone in danger never needs an account. To keep the trial fair, each phone and each email can start a trial only once. Nothing is ever charged without you choosing a plan.

Signing in

You sign in with Google. Google tells us your email address and confirms that it belongs to you. We never receive your Google password, your contacts or anything else from your Google account.

Around your account we keep only what it needs:

your email address, so we can help you if you write to us;
a coded form of your Google account number, so you can sign in again even if your email changes;
the day your free trial began, your plan, and which phone you are signed in on;
a one-way coded mark of your email and phone, kept after you delete your account, only to stop a second free trial. It cannot be turned back into your email.

Your conversations still stay on your phone; an account does not upload them to us. If someone else signs in on the same phone, they do not see yours.

Backing up to your own Google Drive

Because we keep no copy of your conversations, losing your phone would mean losing them. So you can choose to back them up to your own Google Drive. It is off until you switch it on, and Google asks your permission when you do.

The backup goes into a hidden area of your Drive set aside for this app. The app can reach only that area, not your other files, photos or documents.
We never see the backup. It goes from your phone to your Drive directly, without passing through our server.
It is as private as the rest of your Google Drive. It is not separately locked with a password.
You can delete it at any time: in Google Drive, open Settings, then Manage apps, find Philosopher In My Pocket, and choose Delete hidden app data. Switching the backup off in the app stops new backups.

Who helps us run the app

We use a small number of service providers: Cloudflare for hosting, Google for the AI that writes answers, for sign-in and (only if you switch it on) for your Drive backup, and DeepInfra for reading answers aloud. Each receives only what it needs for its task. They may process data outside India, and none receives your data from us for advertising.

If you buy a plan, the payment is handled by Paddle on the web, or by Apple or Google if you buy inside their app stores. They collect your payment details themselves; we never see your card or bank details. We receive only what we need to run your plan: that it is paid, until when, and a customer number so you can manage or cancel it.

Deleting your data

Conversations: delete any conversation in the app, or delete everything by clearing the app's data or removing it from your phone. Because we never had a copy, it is gone for good, and we cannot bring it back. If you switched on the Drive backup, delete that too (see above).
Your account: in the app, open Account, then Your account, and choose Delete account, or write to satyartha.work@gmail.com. Your email, your plan and your account are deleted. The only thing kept is the scrambled mark that stops a second free trial, described above.
The usage totals contain nothing about you, so there is nothing in them to delete.

Your rights

Under India's Digital Personal Data Protection Act, 2023, you can ask what we hold about you, ask us to correct it, ask us to delete it, and name someone to act for you. If you live in the European Union or the United Kingdom, you have similar rights under the GDPR, including the right to complain to your local data protection authority. Write to satyartha.work@gmail.com and we will reply within 30 days. If you are not happy with our answer, you can raise a complaint with our grievance officer, Satyartha Saxena, at the same address.

Age

The app is for people aged 13 and over. If you are under 18, please use it only with your parent's or guardian's permission. We do not ask your age and do not knowingly hold data about anyone under 13; if a parent tells us a child under 13 has an account, we delete it.
