Rainwater Harvesting
Learn to plan, build and maintain a safe, resilient rainwater harvesting system — one clear plate at a time. Rainwater Harvesting is a field manual you can actually follow: ten guided lessons walk you from your roof to a healthy tank, teaching the four essential steps most beginners miss (prefilter, calming inlet, floating intake, skimming overflow). The signature Watershed diagram builds itself and fills with water as you complete each plate, earning amber Guardian Seals along the way. A grounded calculator turns your roof size and local rainfall into real gallons, a recommended tank, and how much of your garden or home it can cover — using the standard formulas, never guesses. Then a maintenance tracker keeps it running for years with next-due dates, seasonal checklists, and an equipment log. Check your state's rules, browse ranked water-use ideas, and keep everything non-potable-safe with clear guidance. No ads, no AI gimmicks — just the trustworthy build-along coach the category has been missing.

Privacy Policy

Effective July 27, 2026 · Last updated September 14, 2026

Forgotten Rain LLC ("we", "us") operates the Rainwater Harvesting mobile application (the "App"). This policy explains what we collect, how we use it, and the choices you have.

Information we collect

What we do not collect

We do not collect your location, contacts, photos or media files, or advertising identifiers, and we do not use any third-party advertising or behavioral-tracking SDKs. We do not use any analytics, attribution, or crash-reporting SDKs. We do not track you across other apps or websites.

Reminders & notifications

If you turn on maintenance reminders (part of Rainwater Harvesting Pro), the App schedules local notifications on your device for 9 AM on the day a maintenance job or part replacement is due. They are created on your device from your own maintenance schedule — we do not operate a push-notification server, and nothing is sent to us to deliver them. You can turn reminders off in the App's Settings, or turn notifications off in your device settings.

How we use information

To provide and maintain the App, authenticate you, sync your content to your account, and respond to support requests. We do not use your content for advertising.

Storage, security & processors

Your data is stored with our cloud backend (Supabase), isolated per user with row-level security so that only you can access your own data, and transmitted over encrypted connections (HTTPS/TLS). A copy of your data is also cached on your device so the App stays fast and works offline; removing the App, or clearing its data, deletes that local copy. We share data only with the limited service providers needed to run the App — our cloud hosting and authentication provider, and Apple (for any purchases). To confirm whether a purchase is active we use RevenueCat, which receives an app user identifier (a random one before you sign in, and your account's internal ID after — never your name or email), the purchase details Apple provides, and basic device information such as platform, operating-system version, and country. We do not sell your personal information.

No method of storage or transmission is completely secure, so while we work to protect your information we cannot guarantee absolute security.

International users

Our service providers may process and store information on servers in the United States or other countries, whose data-protection laws may differ from those where you live, under the terms of those providers.

Data retention & deletion

We retain your data while your account is active. You can permanently delete your account and all associated data at any time from within the App (Settings → Delete Account). Deletion removes your account and content from our systems.

Records of purchases are kept by Apple, and subscription status by RevenueCat, under their own policies, because they are needed for billing, entitlement, and tax purposes. Deleting your account does not delete those records, and it does not cancel an active subscription — cancel that in your Apple ID settings.

Children

The App is not directed to children under 13, and we do not knowingly collect personal information from them.

Your choices

You can access, correct, or delete your data using the in-app controls, or by contacting us at [email protected].

Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your personal information, to object to or restrict certain processing, and to complain to your local data-protection authority. Most of this you can do with the in-app controls; for anything else, email [email protected] and we will respond as required by applicable law.

These pages

These Privacy, Terms, and Support pages are static: they set no cookies and load no analytics, advertising, or third-party scripts. Our hosting provider may keep standard request logs (such as IP address and browser type) to serve the pages securely and diagnose faults. If you email us, we keep your message and address only to reply and help you.

Changes

We may update this policy from time to time; material changes will be reflected by a new effective date above.
