1. Who this policy covers
This Privacy Policy explains how Kisan Calculator: Farming Tools ("the App", "we", "us") handles information when you use it. It applies to all users of the App, in any of its supported languages (English, Hindi, Gujarati, Marathi, Punjabi, Bengali, Telugu).
2. Information the App stores
The App does not have user accounts, sign-in, or cloud sync. All information below is saved only in the App's private storage on your own device (using Android's local database and preferences storage), and is never transmitted to us or to any server we operate.
Information you choose to enter
| Feature | What may be stored, if you use it |
|---|---|
| Tractor Calculator & Tractor Timer (Saved History) | Farmer name, date, rate entered, working time / trip count / area, and the calculated total amount |
| My Book (lending records) |
Person's name, an optional mobile number, principal amount lent, interest rate/type, the date the
loan was given, notes, and a history of any partial payments recorded (amounts, discount, dates, notes).
Please note: this feature involves entering information about other people you know (e.g. someone you've lent money to), not just about yourself. This data is stored only on your device, for your own record-keeping — please use it responsibly and only for people you have a legitimate reason to keep such records about. |
| App preferences | Your selected display language |
| Crop Calculator | Generates a PDF report of your calculation, saved to your device's own Downloads folder (like any file you save from any app) - not stored by or sent to us. |
Information we do not collect
We do not collect your name, phone number, email address, location, contacts, photos, or any other personal information about you, except what you voluntarily type into the features listed above - and even that never leaves your device through any action of ours.
3. Third-party services used by the App
The App uses a small number of third-party services to function. These services may independently collect information under their own privacy policies, which we encourage you to review.
Google AdMob (advertising)
The App shows ads through Google AdMob to support free access to the App. AdMob may collect device and advertising identifiers, general device information, and ad interaction data to show and measure ads, per Google's Privacy Policy. You can manage ad personalization for your device in your Android device's Google Settings (Settings > Google > Ads).
WhatsApp ("Send on WhatsApp" buttons)
Several screens let you share a calculation summary via WhatsApp. Tapping this only opens WhatsApp with a pre-filled message that you review and send yourself - we do not access your WhatsApp account, contacts, or messages, and nothing is sent unless you choose to send it.
External links ("Explore More" screen)
Some screens link out to external websites, opened in an in-app browser tab. Once you're on one of those sites, that site's own privacy policy applies, not ours.
4. Permissions the App requests, and why
| Permission | Why the App needs it |
|---|---|
| Internet / Network State | To load ads through Google AdMob |
| Notifications | To show the Tractor Timer's running-timer notification while it's active, so you can see it without keeping the App open |
| Foreground Service | To keep the Tractor Timer counting accurately in the background - for example if you lock your phone or switch apps while it's running |
| Storage (Android 9 and earlier only) | To save Crop Calculator PDF reports to your device's Downloads folder. Not needed on Android 10+, which handles this without a separate permission |
We request only the permissions each feature genuinely needs, at the time you use that feature.
5. How your data is stored and secured
Everything described in Section 2 is stored in the App's private, sandboxed storage area, which Android keeps isolated from other apps on your device. The one exception is PDF reports you choose to export from Crop Calculator, which are saved to your device's shared Downloads folder like any other file you save - and are therefore subject to your device's normal file access rules, the same as any other file you download or save there.
6. Your choices and control over your data
- You can delete individual Saved History or My Book entries at any time from within the App.
- You can delete all Saved History at once using the delete-all option on that screen.
- Uninstalling the App permanently deletes all locally stored data described in this policy.
- You can manage or opt out of ad personalization through your device's Google Settings, as described in Section 3.
7. Children's privacy
The App is a farming and finance-calculation tool intended for adult use and is not directed at children. We do not knowingly collect personal information from children.
8. Changes to this policy
We may update this Privacy Policy from time to time, for example as new features are added to the App. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this page periodically.
