Plumb — Privacy Policy
Effective date: July 11, 2026
Plumb ("the app") is a construction calculator published by Reliqe LLC. It is built to work
without an account and without collecting personal information.
What we collect
- No account, no personal details. The app has no sign-up. We do not collect your
name, email address, phone number, contacts, or location.
- Purchases. If you buy the one-time Plumb Pro unlock, the purchase is processed by
Google Play or the Apple App Store. To validate the purchase and restore it on your devices, an
anonymous device identifier and the purchase receipt are processed by our purchase-infrastructure
provider, RevenueCat (RevenueCat privacy policy).
We never see or store your payment details.
- Saved history & project sync (Pro, optional). If you use Pro's saved history or
project folders, the calculation entries you choose to save (dimensions, results, project names) are
stored against a random, anonymous key so they can sync across your devices. They are not linked to
your identity.
- Usage analytics. The app keeps a small in-app event log (for example, "calculation
completed") on your device to improve the product. These events are anonymous.
What we don't do
- No ads and no advertising SDKs.
- We do not sell data — there is nothing personal to sell.
- No tracking across other companies' apps or websites.
Data deletion
Saved history and projects can be deleted in the app at any time, which removes them from sync
storage. To request deletion of anything else (for example, purchase-validation records), email us at
the address below and include your device's restore ID from Settings → Support.
Security
All data in transit is encrypted (TLS). Synced entries are stored with reputable cloud infrastructure
providers.
Children
Plumb is a general-audience utility and is not directed at children under 13.
Changes
If this policy changes, the updated version will be posted at this address with a new effective date.
