Privacy policy

Lido Pool is an app for looking after pool and hot tub water. We built it so that it works without an account and keeps your information on your phone.

What the app stores

Your pool details (size, type, products you use), your test results and the steps you mark as done are saved only on your device. We do not have a server that receives them, and we cannot see them. Deleting the app deletes this data.

Reminders

Reminders (for example "time to test" or "ready to swim") are scheduled by your phone. Nothing is sent to us. You can turn them off in iOS Settings.

Purchases

Subscriptions are handled by Apple. To check whether you have an active subscription, the app uses RevenueCat, which receives an anonymous app user ID and your purchase receipts from Apple. We never see your name, email or payment details. See RevenueCat's privacy policy.

Crash reports and usage statistics

To fix bugs, the app may send crash reports (device model, iOS version, app version and what the app was doing when it crashed) to Sentry. To learn which features are used, it may send anonymous usage signals to TelemetryDeck, which does not collect names, emails, IP addresses or advertising identifiers. Neither contains your test results or pool details.

Camera, photos and files

You can photograph or pick a picture of a pool shop report, a product label or a test strip, or open a PDF report from your email. The text is read on your device by Apple's built-in text recognition (Vision and PDFKit). The picture or file is not uploaded anywhere and is not kept by the app: only the numbers you confirm are saved, as part of your test.

A shop report can show your name, address or phone number. The app does not save them.

The app asks for camera access only when you choose to take a photo. When you pick a photo, iOS shows you its own picker and the app receives only the photo you select, not your library. You can change camera access at any time in iOS Settings → Lido Pool.

Website

The calculators on this website run in your browser. We do not use advertising cookies or trackers. Our hosting provider, Cloudflare, may keep standard server logs for security.

If you leave your email to hear when the app is out, we store that address with Cloudflare and use it only for that one email about the launch. We do not share it, and you can ask us to delete it at any time.

Children

Lido Pool is not directed at children under 13 and does not knowingly collect their data.

Your rights and contact

Because your data stays on your device, you control it: you can edit or delete it in the app at any time. For any question about privacy, write to support@lidopool.com.

If this policy changes, we will update this page and the date above.
