Privacy Policy

Last updated: 7 November 2026 (Jobsite Calc Pro and Adapty added before the first release)

Jobsite Calc: Construction is an app from Itworked Systems, a company registered in Türkiye. This page explains what the app does with information. In short: your measurements, lists and projects stay on your phone; the app talks to one service, Adapty, only to sell and check Jobsite Calc Pro.

Itworked Systems is responsible for the app under Turkish data protection law (KVKK, Law No. 6698) and, for users in the EU and the UK, the GDPR.

The short version

Nothing you measure, calculate, list or save in the app is sent to us or to anyone else.
There is no account, no sign-in, no ads and no tracking. The calculators work fully offline.
When the phone is online, the app sends a random install ID, app opens and, if you buy Pro, your purchase record to Adapty, the service that handles our in-app purchases. It is not linked to your name or any account, not used for advertising, and not used to track you across apps or websites.
We never sell your information.

What stays on your phone

Your settings (units, fraction precision, default waste allowance and key vibration).
Your history of calculator answers (up to the last 1,000).
Your materials list and saved projects.

These are saved in the app's own storage on your device. We cannot see them. Deleting the app deletes them. Your phone's own backup (iCloud or Google) may include them, under Apple's or Google's terms.

Purchases (Adapty)

Jobsite Calc Pro is sold through the App Store or Google Play. Apple or Google takes the payment; we never see your card or payment details. To offer the plans and check whether Pro is active on your phone, the app includes the Adapty SDK from Adapty Tech Inc. (adapty.io), which processes this data for us as a service provider. When the phone is online it sends Adapty:

a random ID made for this install of the app, and the app vendor ID the phone gives every app (neither is your name, email, phone number or an advertising ID);
when the app is opened and when the Pro plans are shown;
basic technical facts: app version, phone model, operating system version, language, region setting and time zone;
your purchase history for Jobsite Calc Pro (which plan, when, and whether it is active), if you buy or restore it.

We switched off the collection of the advertising identifier (IDFA on iPhone, Advertising ID on Android) and of IP addresses in the app. Adapty stores this data on its servers, which may be outside Türkiye and the EU (Adapty's privacy policy: adapty.io/privacy); international transfers are protected by standard contractual safeguards. We use the data only to provide Pro, to count installs and purchases, and to keep the app working, and we keep it while the app is offered. Our legal bases are the contract with you (for purchases) and our legitimate interest in running the app. If you want the data for your install deleted, email us; because it is anonymous, tell us roughly when you installed the app and your phone model, or simply delete the app, which ends the collection. Purchase records that Apple or Google keep are handled under their terms.

The app does not use your camera, microphone, location, contacts, photos or files, and it does not ask for those permissions.

When you choose to share

The Send PDF estimate and Share as text buttons create the estimate on your phone and open your phone's share sheet. Where it goes (a message, an email, a file) is your choice, and the app it goes to handles it under its own terms. The links to this website open in your browser; our host Cloudflare processes the request to deliver the page, and we run no analytics on these pages.

Delete your data

Jobsite Calc has no accounts. To delete everything stored on your phone (settings, history, materials lists and projects), delete the app. To have the anonymous Adapty data for your install deleted, email info@itworkedsystems.com with the subject "Jobsite Calc data deletion" and tell us roughly when you installed the app and your phone model. We delete the install ID, app-open and plan-view events and the purchase history Adapty holds for it within 30 days and confirm by email. Purchase and payment records kept by Apple or Google are handled under their terms, and we keep nothing else.

Your rights

Under Turkish data protection law (KVKK, article 11) and the GDPR you can ask whether we process data about you, and ask for access, correction, deletion or objection. The only data the app sends is the anonymous data described above. If you email us, we use your message only to answer it and delete it when it is no longer needed. You can also complain to Türkiye's Personal Data Protection Authority (Kişisel Verileri Koruma Kurumu) or, if you live in the EU or the UK, to the data protection authority where you live.

Children

The app is a general tool, not made for children, and it collects no personal information such as names or contact details from anyone.

Changes

If the app ever starts using data in a new way, we update this page and the date at the top before that version is released.
