Privacy Policy — Charvaha

Who we are

Charvaha (“we”, “us”) is a mobile app for farms and their customers. Farms keep records of livestock — identity, health, weight, photos, vaccinations, and ownership. Customers see the animals linked to their phone number, along with the farm’s public profile.

This policy explains what information the app handles, why we need it, and how we protect it. It applies to the Charvaha app (Android package com.charvaha.app) and this website.

We do not sell or share your data

We do not sell, rent, or trade personal information. We do not share it with advertisers, data brokers, or other third parties for marketing. We do not show ads, and we do not build advertising profiles.

Information is used only to run Charvaha: to create your account, store the records you enter, show those records to the farm and the customer they belong to, and keep the app reliable.

Information we collect

You provide this information when you create an account or use the app:

Account. Full name, email address, password, phone number (with country code), account role (farm or customer), and an optional profile photo.
Farm profile. Farm name, description, address, contact email, contact phone, animal types, logo, and farm gallery photos.
Animal records. Details a farm enters, such as species, breed, sex, physical tag, name, owner phone number, weight, height, health and quarantine status, notes, vaccination history, update history, and photos.

The app also handles a small amount of technical information needed to operate:

Sign-in session. A secure session so you stay signed in.
Device connectivity. Whether the device is online, so offline farm records can sync when a connection returns.
Diagnostics. If error reporting is enabled, crash and error reports that include an internal account id and role. We do not attach screenshots, session recordings, or your name, email, or phone number to those reports.

We do not collect your location, contacts, payment details, advertising id, or health information about people. Health fields in the app describe animals only.

How we use information

Create and secure your account, including email-and-password sign-in.
Verify sensitive farm actions — such as onboarding, handover, and transfers — with a one-time code sent to the relevant phone number.
Store animal, vaccination, photo, and farm records so farms can keep an accurate history.
Show a customer only the animals registered to their phone number, plus the farm’s public profile and gallery.
Let you place a phone call or open WhatsApp when you choose to contact a farm or customer. Charvaha does not upload your contact list.
Diagnose crashes and fix reliability problems.

Who can see your information

Farm accounts can see the records they create. A customer account can see animals linked to that customer’s phone number, and the farm profile and gallery the farm has published. Other users cannot browse your account or unrelated animals.

Phone numbers are used to match an animal to its customer and to send one-time verification codes for critical actions. They are not published as a public directory.

How we protect information

We use secured mechanisms for storage and transmission:

Encrypted transmission. Data sent between the app and our services travels over HTTPS (TLS).
Access control. Records are available only to a signed-in account that is allowed to see them.
Encrypted offline storage. When a farm works offline, pending records and photos are encrypted on the device. Database contents use SQLCipher. Photo files use AES-256-GCM. Encryption keys are kept in the Android Keystore or iOS Keychain and are not synced to other devices.
Limited diagnostics. Error reports are configured so they do not include screenshots, session replay, or default personal details beyond an internal account id and role.

No method of transmission or storage is perfectly secure. We design Charvaha so that farm and customer data stays limited to the people and systems that need it to provide the service.

Photos and device permissions

The camera and photo library are used only when you choose to add an animal photo, a farm gallery image, or a profile image. We do not access the camera or your photo library in the background.

Photos you upload are stored in cloud object storage and delivered over HTTPS so they can appear in the app for the farm and the linked customer.

This website

The website is static. The contact form does not store what you type. It opens your email app so you can send the message yourself. Pages may load the Inter typeface from Google Fonts and Bootstrap from a content network. Those requests can include a network address. They do not include your account, animal, or farm records.

Service providers

A few companies process data strictly so Charvaha can function. They are not allowed to sell it or use it for their own marketing.

Supabase — account authentication and the application database.
Cloudflare R2 — storage of photos and images you upload.
Sentry — crash and error diagnostics, limited as described above.
Google Fonts — the Inter typeface may be downloaded to display the interface. That request can include a network address. It does not include your account, animal, or farm records.

How long we keep information

We keep account and livestock records for as long as the account is active and the records are needed to provide Charvaha. Offline data that was never uploaded is stored only on that device. Clearing the app’s data or uninstalling the app removes those local copies.

You can ask us to delete your account and the personal information tied to it. Email us from the address registered on the account so we can confirm it is you. We may keep a limited record where the law requires it, or where another user’s animal history must stay accurate after a handover — for example, a farm’s record that an animal was handed to a customer.

Your choices

Update your profile and farm details inside the app.
Choose which photos to add, and remove farm gallery photos you uploaded.
Sign out at any time.
Request access, correction, or deletion of your personal information by contacting us.

Children

Charvaha is a tool for farms and adult customers. It is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has created an account, contact us and we will delete it.

Changes to this policy

If we change this policy, we will update the effective date on this page. Continued use of Charvaha after a change means the updated policy applies.

Questions about this policy, or requests to access or delete your data, can be sent to privacy@charvaha.app.

Please write from the email address on your Charvaha account when you ask us to look up or remove your information.
