Android-specific privacy policy. This policy applies only to GrowLux package com.ryantinklepaugh.growlux. It does not change the iOS app’s privacy policy or receipt history.
Scope and controller
Uncommon Weather LLC controls the processing described here. Contact team@uncommonweather.com. GrowLux is a longitudinal canopy-light experiment that repeats a fixed spatial map across the day before and after one recorded intervention.
Information handled
- app-private shelf or zone definitions and fixed 3-, 5-, or 9-point layouts
- on-device camera-exposure or ambient-light readings, survey time slots, dates, source choice, photoperiod, and uncertainty
- one locked intervention, matched before-and-after outputs, weakest-point coverage, seasonal-drift status, and local reports
- purchase entitlement and legal-choice evidence
Camera access is optional and used only to read exposure metadata; camera pixels are discarded and no image is retained or uploaded. A device ambient-light sensor is used only when present and selected. Ordinary experiment data remains app-private and local. A report leaves the app only when you direct an Android share action.
Product storage and providers
GrowLux keeps shelves and zones, fixed layouts, exposure-derived or ambient-sensor readings, AM/midday/PM surveys, the locked intervention, comparison outputs, seasonal status, and reports in app-private local storage. Camera frames are discarded without pixel processing. Reports are created locally for user-directed sharing.
Google Play and RevenueCat process purchase and entitlement state. Supabase receives only privacy-minimal legal-choice evidence. GrowLux has no product-data backend and does not upload canopy records, camera images, or sensor samples.
Legal-choice evidence and abuse prevention
To preserve your choice and prevent forged receipts, the app may send privacy-minimal evidence to Supabase-hosted services: package ID, document versions and hashes, acceptance or withdrawal state, coarse adult age band and role, timestamps, a random installation identifier, request identifiers, an Android Keystore public-key proof, and—when configured—Google Play Integrity verdict material. We also process connection metadata such as IP address, user agent, response status, and rate-limit state for security, reliability, and abuse prevention. We do not send your ordinary product records with legal-choice evidence.
Purchases
Google Play supplies transaction and purchase-token data, and RevenueCat supplies entitlement and offering state. We do not receive your full payment-card number.
Retention and deletion
Local records remain until the user deletes an experiment or all app data or removes the app. Temporary report files follow app-cache and deletion behavior. A deliberately shared report remains with the selected destination until removed there. Legal-choice evidence follows the separate evidentiary retention described below.
Server-side legal evidence is retained to prove and honor the choice, withdrawal, integrity, and retry history it records. Security logs are retained only as reasonably needed for fraud prevention, troubleshooting, and legal compliance. Contact us to request access or deletion; we may retain evidence where necessary to establish, exercise, or defend legal claims.
Choices and rights
You can deny optional Android permissions, decline or withdraw legal consent, manage purchases where applicable, and request privacy help. Depending on where you live, you may have rights to access, correct, delete, restrict, object, or appeal. We do not discriminate for exercising a privacy right.
Age boundary
The app is not directed to anyone under 18. We do not knowingly collect a precise birth date through the legal-choice flow.
Security and transfers
We use reasonable technical and organizational safeguards, but no device, network, or storage system is guaranteed secure. Providers may process information in the United States or other countries subject to applicable safeguards.
