Privacy Policy

Last updated: 2 November 2026

The short version. Condbend does its work entirely on your phone. The free calculators need no account. Pro is tied to an account you create with Sign in with Apple or Sign in with Google, so it follows you to a new phone. There are no ads and no advertising or behavioural tracking. Your measurements and settings never leave your device. Three things do leave it: your sign-in account details if you sign in, what is needed to process and restore a purchase, and an automatic report if the app crashes.

Who we are

Condbend is developed by Umut Fidan (DataStructBlues). You can reach us at contact.umutfidan@gmail.com.

Information stored on your device

The app saves the following in its own private storage so it behaves sensibly between sessions. This data is never transmitted to us or to anyone else, and it is removed when you uninstall the app:

Your unit system (imperial or metric) and theme preference.
Whether you have completed the introduction screen.
The values you last entered in each calculator, so a screen reopens where you left it.
A flag recording whether Pro is unlocked.

Your account

Signing in is optional for the free calculators and required to buy or restore Pro. You sign in with Apple or Google; Condbend has no passwords of its own. Accounts are managed for us by Firebase Authentication, a Google service, which receives:

A unique account identifier issued by Firebase.
The identifier Apple or Google uses for you with Condbend.
Your email address and, if you share it, your name. With Sign in with Apple you can choose Hide My Email, in which case we only receive an Apple relay address.
When the account was created and last signed in.

We use these only to keep you signed in, to attach your purchase to your account, and to answer you if you contact support. We never see your Apple or Google password. See the Firebase privacy documentation.

Information related to purchases

If you buy a subscription or the lifetime unlock, purchase processing is handled by Apple or Google, and subscription state is managed for us by RevenueCat, Inc. We never see or receive your card number, billing address, or Apple/Google account details.

To make purchases work across sessions and support restoring them, RevenueCat receives:

Your account identifier (the Firebase one above), so the purchase belongs to your account rather than to a single phone. RevenueCat does not receive your email address or name.
The purchase receipt issued by the App Store or Google Play, and the status of your subscription.
Basic technical context such as device platform, app version, and store country.

RevenueCat processes this on our behalf as a service provider. See the RevenueCat privacy policy, the Apple privacy policy, and the Google privacy policy for how each of them handles data.

Crash reports

When the app crashes, a diagnostic report is sent automatically so the fault can be found and fixed. This is handled by Firebase Crashlytics, a Google service. A report contains:

The stack trace of the crash — which lines of our code failed.
Device model, operating system version, and app version.
The state of the device at the time, such as available memory and whether the app was in the foreground.
A Firebase installation identifier: a random, resettable ID for the app on your device. It is not your name, email, or an advertising ID, and reinstalling the app produces a new one.

Crash reports are used only to fix defects. We do not enable Google Analytics, so no behavioural or usage events are collected alongside them. See the Firebase privacy documentation for how Google processes this data.

Because the calculators run offline and hold no personal data, a crash report cannot contain your measurements or job details.

What we do not do

We do not collect your phone number or location, and we only receive your name and email address through the sign-in described above.
We do not use advertising, behavioural analytics, or cross-app tracking SDKs, and there are no ads in the app.
We do not sell or share personal information.

Children

Condbend is a professional tool for electricians and is not directed at children. We do not knowingly collect information from children under 13.

Your choices and rights

Delete your account in the app: Settings → Account → Delete account. This permanently deletes your Condbend account and, for Sign in with Apple, revokes Condbend's access to your Apple ID. A store purchase stays with your App Store or Google Play account and can be restored after you sign in again. Deleting the account does not cancel a subscription — cancel it in your App Store or Google Play settings. You can also request deletion by email without the app.

To have your purchase record at RevenueCat deleted as well, or for any other request to access or correct your data, email us and include the Support ID shown under Settings → Account.

Uninstalling the app removes everything stored on your device, and the installation identifier attached to any crash report is discarded with it.

Changes to this policy

If this policy changes, the revised version will be posted on this page with a new date above. Material changes will also be noted in the app's release notes.
