Privacy policy
Version 2026-09 · HydroHome KH · [company legal name, address] · Privacy contact: [email]
Draft for legal review. This text describes how HydroHome KH actually works. Before selling units, have it checked by a lawyer familiar with Cambodian law (including the Law on Electronic Commerce and the Law on Consumer Protection) and fill in the company details marked [ ].
What we collect
- Account: email address, and if you choose: name, phone number, province, language.
- Your unit: sensor readings (water and air temperature, humidity, EC, pH, tank level), settings, events, calibration, tank and pipe sizes, your water log.
- Your farm: racks, plantings, nursery batches, harvests (weights, dates), supplies, Plant Doctor reports and photos you add.
- Community and Market: posts, comments, photos, likes, listings, reservations, ratings, buy-back offers, supply orders, and — only if you save it — your pickup address and contact.
- Telegram: if you connect it, your Telegram chat ID (to send you alerts).
- Technical: sign-in records and security checks (Google reCAPTCHA via Firebase App Check) that prove requests come from our website.
Why we use it
- To run your unit, the app, alerts and feeding suggestions.
- To verify harvests fairly for the leaderboard, badges and the Market.
- To run the Market and supply orders you choose to use.
- To support you when something goes wrong.
- To improve growing advice — only from data you choose to share ("Share anonymous data"), without names, notes, photos or locations.
Who can see what
- Family members you invite can see your unit and farm (read-only).
- Other users see only what you publish: your community name, posts, listings (district and province, not your address) and your level/badges.
- A buyer sees your pickup address and phone only after you accept their reservation; it is removed after collection.
- HydroHome staff can see each unit's technical health (online, firmware, sensor faults) to keep the service running. They can see your profile and farm, or change your settings, only with a one-time support code you create (Settings → Get help from HydroHome), for at most 2 hours; you can end it any time and see what they did.
- Service providers who process data for us: Google Firebase / Google Cloud (database, storage, sign-in, functions — region asia-southeast1, Singapore), Cloudflare (website hosting), Telegram (only if you connect it), Open-Meteo (weather — only the coordinates of your province, no personal data).
- We do not sell your personal data.
How long we keep it
- While your account exists. Unit readings are kept for about 90 days on the unit's history.
- Database backups are kept for 30 days, then deleted automatically.
- When you delete your account, your profile, farm, posts, photos, listings, achievements and Telegram link are deleted. Records of buy-back payments and supply orders are kept without your name, phone or notes where needed for accounting and tax.
Your choices and rights
- Download your data: Settings → Your data → Download.
- Delete your account: Settings → Your data → Delete my account.
- Correct your details in Settings at any time. Switch data sharing and each Telegram alert on or off.
- Questions or requests: [privacy contact].
Security
Access is controlled by sign-in and server-side rules; connections are encrypted; units have their own limited accounts. No system is perfectly secure — tell us immediately if you suspect a problem.
Children
The service is for adults. Children may use a unit under a parent's account and supervision.
Changes
We will ask you to accept important changes in the app.
