Mavuno Privacy Policy

1. Who we are

Mavuno (shown on Google Play as Mavuno: Crop Doctor & Advice) is a voice-first crop advisory mobile app operated by Bery Health and Supplies LLC (Wyoming). References to "we", "us", or "our" in this policy refer to Bery Health and Supplies LLC (Wyoming) as the data controller.

Mavuno is a work in progress: we are still improving its answers and its crop checks, and this page will change as the app does.

For privacy-related enquiries, contact us at henry@fieldhealthafrica.org.

This page covers the Mavuno mobile app (Android package com.mavuno.mavuno). The FieldHealth Africa website has a separate website privacy policy. To delete your account or your data, see Delete your Mavuno account.

2. What Mavuno collects

Most of Mavuno works on your phone without an account or a signal. We collect only what you give it, or what a feature you use needs:

• Account: if you sign in, your email address and a user ID (sign-in by emailed code), or your Google account's email and user ID (Google sign-in). Sign-in is optional.
• Farm profile: your language and your crops, and, only if you choose to add them, your phone number and your farm coordinates. Kept on your phone, and copied to your backup if you sign in. Coordinates are kept only in your backup; they are not sent with your questions or photos.
• Photos: plant and product-label photos you take or pick. Before a photo leaves the phone, Mavuno removes its EXIF data, including any GPS position the camera wrote into it. Photos are sent through our gateway to Anthropic's Claude API for checking, and are backed up in Supabase if you sign in.
• Questions, chats and diagnoses: what you ask, the AI chats, the diagnoses and the answers, so you can read them again. If you sign in, these are kept in your Supabase backup.
• Approximate location: only if you allow it during setup, read once at low accuracy. Mavuno does not ask for precise location, and does not send your location with questions.
• Email for news: only if you tick the box to receive guides and product news. Giving an email to sign in or back up is not agreement to be written to.
• Install ID: a random number made when the app is installed and sent with online requests to count use fairly. It does not come from your phone's hardware or any account, and "Clear my data" erases it.
• Usage count: if you sign in, how many online answers your account has used this month, so we can apply the monthly limit.
• Purchase records: if you subscribe, the records of your subscription and payments (see Payments).
• Ads data: collected by Google AdMob to show ads (see Ads and analytics).

Voice: when you speak to Mavuno, your phone's own speech service turns speech into text and reads answers aloud. On most Android phones that service is Google's. Mavuno receives the text, not the recording.

3. Permissions (Android)

The app asks for these. Each one is optional; a feature that needs it stays off until you allow it:

• INTERNET: online answers, sign-in, backup, payments and ads.
• CAMERA: plant and label photos.
• RECORD_AUDIO: speaking your question.
• ACCESS_COARSE_LOCATION: approximate farm region, asked once during setup.

The Google Mobile Ads (AdMob) library also uses your device's advertising ID. You can reset it or delete it in your phone's Settings, under Google, Ads.

4. How we use data

• To answer your questions and check your plant photos.
• To sign you in, back up your farm records and bring them back on a new phone.
• To apply the monthly limit on online answers and, if you subscribe, to open the month you paid for.
• To show ads, through Google AdMob.
• To improve Mavuno: the photos, questions and diagnoses captured by the app help us improve its crop checks and answers.

We do not sell personal data, and we do not use your photos or questions to advertise to you.

5. Who processes it

The check on your phone, the crop library and looking up a product by name work offline and send nothing. When you use online features, these services handle your data, each under its own privacy policy:

6. Payments

Mavuno is free to use. An optional monthly subscription gives you more online answers. You can pay in one of two ways:

• Google Play subscription (mavuno_monthly): Google handles the payment. We receive a purchase token, which we check with Google, and the date the paid month ends. We never see card details.
• MTN or Orange Money through CamPay: the phone number you type is passed to CamPay with the amount, and we do not store it. You approve the payment on your phone with your Mobile Money PIN; we never see the PIN. We keep the payment reference, amount, operator and result.

A subscription is tied to your signed-in account. Google Play and CamPay keep their own records of your payments, under their own policies. CamPay → Google Privacy Policy →

7. Ads and analytics

Ads. The app shows ads from Google AdMob. To show and measure ads, AdMob collects and shares with Google your device's advertising ID, your approximate location (worked out from your IP address), your interactions with the app and its ads, and diagnostic data. Google uses this data under its own policies: how Google uses information from apps that use its services, the Google advertising policy and the Google Privacy Policy. You can reset or delete your advertising ID, or opt out of personalised ads, in your phone's Settings.

Analytics and crash reports. The app's code includes Google Firebase Analytics and Firebase Crashlytics, but they are switched off unless we configure them. If we turn them on, crash and diagnostic data and app usage data are sent to Google. Firebase privacy →

8. Keeping and deleting your data

Data on your phone stays until you delete it. In the app, Profile, "Clear my data" erases your profile, diagnoses, conversations, photos, saved answers and the install ID from the phone.

Your backup (photos, AI chats, diagnoses, profile and optional coordinates) is kept until your account is deleted. Gateway logs that include your user ID are kept for about 30 days and then removed. Google Play and CamPay keep their own records of your payments.

To delete your account and backup, in the app go to Profile, "Delete my account and backup", or email henry@fieldhealthafrica.org; we reply within 30 days. You can also ask by email to delete your data without closing your account. Full steps: Delete your Mavuno account.

9. Your rights

Depending on your jurisdiction, you may have the right to:

• Access the personal data we hold about you.
• Correct inaccurate data.
• Request deletion of your data.
• Object to or restrict certain processing.
• Withdraw consent where processing is based on consent.
• Lodge a complaint with a supervisory authority where applicable.

To exercise any of these rights, email henry@fieldhealthafrica.org.

10. Children's privacy

Mavuno is aimed at adult farmers and agronomy users. It is not directed at children under 16. We do not knowingly collect personal data from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

11. Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top of this page will reflect any changes. Material changes for Google Play and OAuth will keep this same URL path when possible.
