Privacy Policy

Effective date: 15 May 2026  ·  Perpetual Prototypes

1. Who we are

MeadMate is developed and published by Perpetual Prototypes. For privacy questions, contact us at meadmate@perpetualprototypes.io.

2. What data the app stores locally

All of the following is stored only on your device and never transmitted to our servers:

• Batch records (name, dates, gravity readings, notes, status)
• Fermentation logs (specific gravity, temperature, timestamps)
• Recipes, nutrient schedules, and checklists you create
• Photos you attach to batches (stored in your device's local storage)
• Equipment inventory items
• App settings (units, theme, name, notification preferences)

This data never leaves your device unless you explicitly use the backup/export feature, which saves a file to your own device for you to manage.

3. Community features and the data we receive

MeadMate has optional community recipe features. When you use these features:

• Anonymous device ID — A randomly generated UUID (e.g. a1b2c3d4…) is created at install time. It is not linked to your identity in any way. We use this to attribute recipe submissions and votes, and to prevent duplicate votes.
• Recipe submissions — If you choose to submit a recipe to the community library, the recipe content (ingredients, method, target gravity) and your anonymous device ID are sent to our API. No personal information is included.
• Votes (up/downvote) — Your anonymous device ID and the recipe ID are recorded when you vote. No personal data is transmitted.

We do not collect your name, email address, phone number, precise location, contacts, payment information, or any other personally identifiable information.

4. Data we receive automatically

Our API server (hosted on Cloudflare Workers) receives standard web request metadata when you use community features, including:

• IP address (retained for up to 24 hours in Cloudflare's access logs, then discarded)
• Request timestamp and HTTP method
• App version string

We do not use this information to identify individuals and we have no analytics platform installed.

5. Hosting and infrastructure

Our API and website are hosted on Cloudflare (Cloudflare, Inc., USA). Cloudflare's privacy policy applies to infrastructure-level data. We do not use Google Analytics, Firebase Analytics, Meta Pixel, or any third-party analytics service.

6. Push notifications

If you enable reminders, MeadMate schedules local push notifications on your device using the operating system's notification API. These notifications are generated and delivered entirely on-device — no notification content is transmitted to our servers.

7. Photos

Photos you attach to batches are stored in your app's local storage. They are not uploaded to any server. If you share a PDF export, any photos included are sent only to whatever destination you choose (e.g. your email client or a messaging app).

8. Data retention and deletion

• Local data — Deleted when you uninstall the app, or via the in-app data management options.
• Community submissions — Recipe submissions and votes tied to your anonymous device ID can be removed on request. Email us with your device ID (visible in Settings) and we'll delete associated records within 30 days.
• Server logs — Standard Cloudflare logs, retained for up to 24 hours.

9. Changes to this policy

If we make material changes, we'll update the effective date above. We won't suddenly start collecting your data without telling you first.
