Privacy Policy
Habitry is a habit tracker built to keep your data on your phone. This policy explains, plainly, the few cases where something does leave it, who receives it, and what you can do about it. It applies to the Habitry app for Android and to this website.
The short version
- There is no Habitry account. No sign-up, no email address, no password.
- Your habits, logs, notes and experiments are stored on your phone, in an encrypted database. We do not have a copy.
- Cloud AI is optional and off until you turn it on. When you use it, a small, fixed set of details about one habit or experiment is sent to get an answer, and is not stored.
- If the app crashes, a technical crash report is sent automatically. It contains nothing you typed.
- No ads. No analytics or tracking. We never sell or share your data for advertising.
1. Who is responsible
Habitry is published by Deepak Dhanoliya, an individual developer based in India ("we", "us"). For the purposes of India's Digital Personal Data Protection Act, 2023, we are the Data Fiduciary for the limited personal data described below. Contact us at ddtechstudio8@gmail.com.
2. Data that stays on your phone
Everything you create in Habitry — habits, check-ins, notes, reflections, experiments, results, reminders and settings — is stored only on your device, in a database encrypted with a key kept in your phone's secure storage. Android's cloud backup is switched off for Habitry, so this data is not copied to Google Drive either. We cannot see, access or recover it.
If you create a backup file with Export, it is encrypted with a password you choose and saved or shared wherever you send it. We never receive it.
3. Data that leaves your phone
3.1 Cloud AI (optional, Habitry Pro)
Cloud AI is off by default. It only runs after you turn it on in the app, and only when you ask it something. Requests go over an encrypted (HTTPS) connection to our server on Cloudflare, which passes them to an AI model hosted by Cloudflare (Workers AI) and returns the answer.
Experiment Coach sends:
- the habit's name and type, if there is one, and the goal you type into the AI box;
- your completion rate for that habit, as a percentage;
- Habitry's own list of built-in experiments and building blocks, so the AI can suggest one that exists.
Result Interpreter sends:
- the experiment's name, your hypothesis, and how many days it ran;
- the two numbers being compared, what they measure, and how many days are behind each;
- the difference the app already calculated.
Never sent: your notes, reflections and anything you write in a daily log; habits other than the one you are asking about; your history of logs or the database itself; any identifier for you, your habit or your device.
Our server does not store requests or answers. Its logs record only technical facts — which feature was used, whether it succeeded and how long it took — never the content.
3.2 Anonymous sign-in and app verification (only with cloud AI)
To stop our AI server being abused, the first time you use cloud AI the app creates an anonymous account with Google Firebase Authentication. It is a random identifier with no name, email or phone number attached, and nothing on our server is linked to it. Firebase App Check, using Google Play Integrity, confirms that requests come from a genuine copy of the app.
Turning cloud AI off signs the app out of this account. Firebase deletes anonymous accounts automatically after 30 days of inactivity.
3.3 Crash reports (always on)
When the app crashes or hits a serious error, it automatically sends a crash report to Sentry, our error-monitoring provider, so we can find and fix the bug. A report contains the type of error, a technical stack trace, and your device model and Android version. Reports are filtered before they leave the phone so they cannot contain habit names, notes or anything else you typed, and they carry no user identifier. Sentry keeps crash reports for a limited period set by its data-retention policy and then deletes them. There is no in-app switch to turn this off; if you do not want crash reports sent, please do not use the app.
3.4 Purchases
Habitry Pro is sold through Google Play Billing, as a subscription or a one-time lifetime purchase. Google handles your payment details under its own privacy policy; we never see your card or bank information. The app only learns whether you have an active subscription or a lifetime purchase.
3.5 Network information
Like any internet service, Cloudflare, Firebase and Sentry receive your device's IP address when the app connects to them. Our server uses it briefly to apply rate limits and does not store it.
4. Who receives data
- Cloudflare, Inc. — hosts our server and the AI model (cloud AI only).
- Google LLC — Firebase Authentication and App Check (cloud AI only), and Google Play Billing.
- Functional Software, Inc. (Sentry) — crash reports, stored in the United States.
These providers act on our behalf and may process data outside India, including in the United States. We do not sell personal data, share it with advertisers or data brokers, or use it for profiling. We would disclose data only if required by law.
5. Why we process data
- Cloud AI requests and anonymous sign-in — to provide a feature you chose to turn on (your consent), which you can withdraw at any time by turning it off.
- Crash reports — to keep the app working and secure.
- Purchase status — to provide the subscription you bought.
6. Your choices and rights
- Delete your data: delete individual habits and experiments in the app, or uninstall Habitry to erase everything stored on your phone.
- Stop cloud AI: turn it off in Settings at any time. Nothing more is sent.
- Take your data with you: use Export to create an encrypted backup.
- Your rights under Indian law: you may ask us for a summary of the personal data we process about you, to correct or erase it, to withdraw consent, to nominate another person to act for you, and to raise a grievance. Because we hold almost nothing that identifies you, we may be unable to match a request to your data, and we will tell you so.
Email ddtechstudio8@gmail.com for any of these. We aim to respond within 30 days. If you are not satisfied with our response, you may complain to the Data Protection Board of India.
7. Security
Data on your phone is encrypted at rest, and everything sent over the network uses HTTPS. You can also lock Habitry with your phone's fingerprint or face unlock and block screenshots. No system is perfectly secure, but we collect as little as possible so there is little to expose.
8. Children
Habitry is intended for people aged 18 and over. Anyone younger should use it only with the consent and supervision of a parent or guardian. We do not knowingly collect personal data from children; if you believe a child has used cloud AI without consent, contact us.
9. Changes to this policy
If we change how Habitry handles data, we will update this page and its effective date, and where the change is significant we will tell you in the app before it takes effect.
