PaycheckPrivacy Policy
Last updated: 7 November 2026
Salary & Paycheck Calculator (on Google Play: Paycheck & Salary Calculator; on your home screen: Paycheck) is an app from Itworked Systems, a company registered in Türkiye. This page explains what the app does with information.
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.
- Everything you type (pay, hours, tips, W-4 and state answers, deductions) and every paycheck you save stays on your phone. The taxes are worked out on the phone.
- The app sends anonymous install and app-open statistics (a random ID for each install and basic device details) to Adapty, the service we use for analytics and for the optional Pro purchase.
- If you buy Pro, Apple or Google take the payment, and Adapty receives the purchase record so Pro can be unlocked and restored.
- No account, no sign-in, no ads, no tracking, no advertising ID, no location. The calculator works without an internet connection.
- We never sell your information.
What leaves your phone, and why
| What | Why | Who receives it |
|---|---|---|
| If you buy Paycheck Pro: what you bought and when, and the store's receipt | To unlock Pro, restore it on a new phone, and count sales | Adapty, which checks purchases for us, and Apple or Google, which take the payment. We never see your card details |
| A random ID made for each install, the app's device ID for our apps (on iPhone, the identifier for vendor), basic device details (such as phone model, system version, language, time zone, store country and app version) and when the app is opened | To count installs and how often the app is used, so we can see whether it is useful and improve it (analytics) | Adapty (Adapty Tech Inc.), which processes it for us |
That is all. The app turns off Adapty's IP address lookup and its advertising ID collection, does not ask to track you, and never sends Adapty your pay, hours, tips, tax answers, state or saved paychecks. The data is not linked to your name or any account (there is none). Your connection's IP address is necessarily seen by Adapty's servers to deliver the request, but the app tells Adapty not to store or use it.

Why we may use this data
For purchases: to deliver what you bought. For statistics: our legitimate interest in understanding how many people use the app and keeping it working well. The statistics are anonymous and minimal, and you can stop them at any time by deleting the app.
How long it is kept
- On your phone: your current numbers, saved paychecks and settings stay until you delete them or the app.
- Purchase records are kept by Adapty for us so Pro can be checked and restored, and by Apple or Google under their own rules.
- Usage statistics are kept by Adapty for us for as long as we use its service for this app, and deleted on request where we can identify them.
Where the data is processed
Adapty is based outside Türkiye and may process data in other countries, including the United States. These transfers follow the rules for sending data abroad in Turkish data protection law and, for users in the EU and the UK, the GDPR.
What the app uses on your phone
- The app's own storage, for the numbers you entered, the paychecks you save, whether you have seen the welcome screens and whether Pro is active. Deleting the app deletes them.
- Sharing (Pro export): when you export a pay stub, the PDF or text is made on your phone and handed to your phone's share sheet. Where it goes next (Files, Mail, a message) is your choice; we never receive a copy.
The app does not use your camera, microphone, location, contacts or photos, and it does not ask for those permissions. Your state is the one you pick; the app never looks up where you are.
App stores and links
Apple and Google run the stores you download the app from, and may collect information about downloads and crashes under their own privacy policies, for example if you choose to share crash reports with developers in your phone's settings. The app links to this website and to the official IRS and state tax publications it uses; if you open those links, your browser visits those websites like any other. On itworkedsystems.com our host Cloudflare processes the request to deliver the page. We run no analytics on these pages.
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 or deletion. We hold almost nothing ourselves; we will help with anything Adapty keeps for us. To ask for deletion of the purchase and usage records kept for this app, email us the anonymous purchase ID shown in the app under More, at the bottom of the About section, so we can find them. 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 not made for children under 13, and we do not knowingly process their data.
Changes
If the app ever starts using data in a new way, we will update this page and the date at the top before that version is released.
