DueTick

Privacy Policy for Android

Last updated: 3 November 2026

This policy explains what happens to your information when you use DueTick, the Android app, and when you contact us. It is written in plain English on purpose, so that you can understand it without reading anything else. If anything is unclear, email us at hello@onemacstudio.in.

This page is for DueTick on Android. DueTick for iPhone has its own Privacy Policy.

1. Who we are

DueTick is made by OneMacStudio, a sole developer based in Tamil Nadu, India ("we", "us", "our"). OneMacStudio is the trading name of the individual developer named as the developer of DueTick on Google Play. For the little personal data described in section 8, OneMacStudio is the data controller, and the Data Fiduciary under India's Digital Personal Data Protection Act, 2023.

For any question or complaint, see section 17.

2. What DueTick stores, and where

Your deadlines

When you add a deadline, DueTick stores what you enter and what it works out from it:

• the name you give it, and a note if you add one;
• its type (Subscription, Expires or One-time), its date, and how often it repeats;
• the day to act by (for example "Cancel by") and when you want to be reminded;
• an amount and its currency, if you add one;
• your answers (such as Cancelled, Keeping, Renewed, Not renewing or Done), any day you asked to be reminded again, and whether you stopped tracking it;
• when it was added and last changed, the time zone your phone was set to when you added it, and a few internal values the app uses to display it.

It also stores your reminder time, which you can change in Settings.

These are kept in two places, both under your control:

1. On your phone, in DueTick's own private storage, which other apps cannot read. The DueTick widget shows your deadlines from there and keeps no copy of its own.
2. In your phone's Google backup, if backup is turned on for your phone. Android copies your deadlines and your reminder time into the backup of your phone that Google keeps in your Google Account, usually about once a day. On Android 9 and later, DueTick takes part only when that copy is end-to-end encrypted with your phone's screen lock (its PIN, pattern or password), so that it can be opened only with your screen lock: neither Google nor we can read it. On a phone without a screen lock, DueTick is left out of the backup. On Android 8, Android's older backup is used, which Google encrypts and keeps under its own privacy policy. Either way, we have no access to your backup: we cannot read, change or delete anything in it. When you set up a new phone by copying your old one to it, the same two things move across.

DueTick does not sync between phones, and keeps nothing anywhere else. If your phone's backup is off, your deadlines are kept on that phone only. If you then uninstall the app, they are gone, and nobody, including us, has a copy.

A few small notes on your phone

DueTick also keeps a few small notes for itself, on your phone only. They are never backed up:

• whether it has already asked you about notifications and exact timing, and shown its tip about your phone's battery settings;
• whether you closed the tip about adding the widget, and when it may show again;
• whether a DueTick widget has ever been added, so that the tip does not come back after you remove one;
• which version of the app last asked Google Play to show a rating request;
• whether Google Play last said you own DueTick Pro, so that the app knows it before Google Play answers again;
• which reminders it has set, so that it can replace exactly those when something changes;
• after you answer a reminder from its notification: which deadline it was about and a copy of that deadline as it was before, so that the app can offer Undo, and, if your answer could not be saved at that moment, the answer itself, until the app saves it. Each is cleared the next time you open the app.

3. What DueTick reads on your phone, and why

To work properly, DueTick reads a few settings from your phone. It uses them on your phone only and never sends them to us:

• your language, region, time zone and 12- or 24-hour clock setting, to show dates, times and amounts the way you expect, to know when your day ends, and to suggest your local currency;
• whether notifications are allowed, and whether last-day reminders may pop up on your screen, so that it can tell you when reminders are switched off or held back;
• whether it may set exact alarms, and whether Android or your battery settings are holding it back, so that it can tell you when reminders may arrive late;
• which company made your phone, so that it can show the battery steps for that phone;
• whether you have added a DueTick widget, and whether your home screen can add one from inside the app, so that it only suggests the widget to people who do not have one, in the way their phone supports;
• whether you own DueTick Pro, which the app checks with Google Play on your phone.

DueTick does not ask for or use your location, contacts, photos, files, camera, microphone, calendar, health data, or any other app's data. It cannot see your Google Play subscriptions, your bank, your cards, your email or your messages. Everything it knows about your deadlines, you typed in.

The permissions it asks for

• Notifications, to show your reminders. On Android 13 and later, DueTick asks you first, after you add your first deadline.
• Alarms & reminders, so that each reminder arrives at your reminder time rather than some minutes later. You can turn it off in your phone's settings; reminders then still come, but may be late.
• Run at startup, because Android removes every app's alarms when the phone restarts. This lets DueTick set your reminders again.
• Google Play billing, to buy DueTick Pro and to check whether you own it.
• Full network access, which DueTick's own code never uses. It comes with Google Play's purchase tool inside the app (Google's Play Billing Library), which sends Google technical reports about its own work: whether its requests to Google Play succeeded or failed, and problems connecting to Google Play. Google uses them to improve that tool and to help with errors, under Google's own privacy policy. They contain nothing you type into DueTick, and we do not receive them.

Your phone may also list a few permissions that come with the standard Android parts DueTick uses to refresh your reminders in the background, such as keeping the phone awake for a moment. DueTick's own code does not use any permission to send your information anywhere.

4. Reminders, the widget and the lock screen

• Reminders are local notifications. DueTick sets them on your phone, as alarms: on the day you choose, at your reminder time (9:00 in the morning unless you change it in Settings), your phone's time, and again that evening and on your act-by day until you answer. No server of ours is involved.
• A reminder shows the deadline's name and its dates, for example Netflix and, under it, Charges Mon 21 Sep — cancel by tomorrow. It never shows the amount.
• From your act-by day, reminders pop up on your screen. They use DueTick's Last-day reminders notification category. You can change how it behaves in your phone's settings, like the ordinary Reminders one.
• The app icon can show a dot or a number, depending on your phone: how many deadlines need your answer.
• The widget sits on your home screen. It shows names and dates, never amounts.
• Anyone who can see your phone can see these: in notifications, including on the lock screen if your phone shows their content there, on the app icon and in the widget. If a deadline's name is private, give it a name only you will recognise, set your phone to hide notification content on the lock screen, or keep the widget off your home screen.
• Background activity. DueTick asks Android to wake it from time to time, to keep your reminders set and the widget up to date, and again after a restart, a change of time, time zone or language, or an app update. Android decides when. Nothing is sent to us.

5. Export a copy

Settings has Export a copy. It makes a spreadsheet file (CSV) of your deadlines, including the ones you stopped tracking: name, type, date, how often it repeats, act-by date, amount, currency, reminders, note and status.

When you tap it, DueTick writes the file in its own temporary folder on your phone and opens Android's share menu. The file leaves your phone only if you share it. The newest copy stays in that folder until your next export replaces it or Android clears it. Once you share it (by email, a message, a files app or anything else), whoever receives it controls that copy, and this policy cannot cover it.

6. Buying DueTick Pro

Google Play handles the whole purchase. We never receive your card or payment details. DueTick checks with Google Play, on your phone, whether your Google Account owns Pro. It keeps Google Play's last answer on your phone, so that it knows before Google Play answers again, and each new answer replaces it. For each purchase, Google gives us an order number, the date, the price and the country (in some countries also the state and postal code, for tax). We use them only for our accounts and to help with refunds. Refunds follow Google Play's refund policies, as the Terms of Use explain.

7. What Google may share with us

DueTick is distributed through Google Play. Google shares some information with app developers:

• statistics, such as installs, uninstalls and ratings, by date, country, phone model and Android version, in a form that does not identify you;
• crash and freeze reports, only if you allowed it. Android lets you choose to share usage and diagnostics data with Google. If you do, Google gives developers technical reports of crashes and freezes, such as the phone model, the Android version and where in the app the problem happened. They do not contain the contents of your deadlines. We use them only to find and fix problems;
• order details for purchases, as section 6 describes;
• ratings and reviews you post on Google Play, which are public.

Google's handling of this information is covered by Google's own privacy policy.

DueTick may ask Google Play to show its rating request after you cancel a paid subscription in time, at most once for each version of the app. Google decides whether to show it. A rating you give there goes to Google Play, like any other rating.

8. When you contact us

Contacting us is always your choice. DueTick works fully without it.

If you email us, we receive:

• your email address, and your name if your email shows it;
• whatever you write, and any attachments you send.

When you write from DueTick's Settings, the subject line names the version of DueTick you have, so that we know which one you mean. You can change it before sending.

We use this only to reply to you and to fix the problem you tell us about. We do not add you to any mailing list, and we never use it for marketing.

Your email is stored by the provider that hosts our mailbox, which handles it only to deliver and keep it for us. That provider may store it outside your country.

We keep an email only as long as we need it to help you and to follow up, and we delete it sooner if you ask. Please do not send us sensitive information, such as passport, card or bank numbers. We never need it to help you.

For readers in the EU and UK: we process your email to answer the request you made, which is our legitimate interest in supporting DueTick.

9. Who we share data with

DueTick shares no data with anyone. It contains no analytics tools and no advertising networks, and no other company, related to us or not, has access to anything you enter. The only part of DueTick that sends anything is Google Play's purchase tool, which reports its own work to Google (section 3). The only other party that ever handles personal data for us is our email host, for emails you choose to send us (section 8).

10. This website

DueTick's pages are part of onemacstudio.in, which has its own privacy policy. In short, the website uses no cookies, no analytics and no trackers, and stores nothing in your browser. Like any website, its host keeps short-lived technical logs, such as IP address and time of visit, to deliver pages and stop abuse.

11. What we never do

• We never sell, rent or trade personal information.
• We never share it for advertising, or build a profile of you.
• We never track you across other apps or websites.
• We never show ads.
• We never use your information to make automated decisions about you.
• We never ask for sensitive data such as passwords, card numbers, health or biometric data.

12. Your choices and your rights

Because we hold none of your app data, you control it directly:

• See or change a deadline: open it in the app.
• Delete a deadline: long-press it, or open it, and choose Delete. It leaves your phone's Google backup the next time Android backs up your phone.
• Delete everything: delete your deadlines in the app, including those under Settings, Stopped tracking, and then uninstall the app. Uninstalling removes everything DueTick stored on your phone. Your phone's last Google backup can still hold a copy, so that a reinstall can bring it back. To remove that copy too, delete your deadlines first and give your phone a day to back up again, or delete your phone's backup in your Google Account (this removes the backup of everything on that phone, not only DueTick).
• Stop backing up: turn off backup in your phone's settings. This applies to your whole phone.
• Stop reminders: turn off notifications for DueTick in your phone's settings.
• Keep a copy: use Export a copy in Settings.

Withdrawing consent. Everything DueTick does with your information follows from choices you made on your phone, and you can undo each one at any time: turn off notifications or backup in your phone's settings, delete a deadline, or uninstall the app. For an email you sent us, ask us to delete it.

Your legal rights. Depending on where you live (for example under India's Digital Personal Data Protection Act 2023, the EU or UK GDPR, or a US state privacy law), you may have the right to access, correct, update, delete or get a copy of personal information about you, to object to or restrict its use, to withdraw consent, and to nominate someone to act for you. The only personal information we could hold about you is an email you sent us. Email hello@onemacstudio.in to use any of these rights, and we will reply within 30 days.

Complaints. If you are not satisfied with our answer, you can complain to the data protection authority where you live. In India, that is the Data Protection Board of India.

Do Not Track. DueTick and this website do not track you, so there is nothing for a browser's Do Not Track signal to turn off. We treat every visitor as if it were on.

13. How long information is kept

• Your deadlines stay on your phone, and in its Google backup, for as long as you keep them. We never hold them.
• Emails you send us are kept until your question is resolved, then only as long as needed for any follow-up, and deleted sooner if you ask.
• Information Google holds, such as purchase records and your phone's backup, is kept by Google under its own policies.

14. Security

Your deadlines are protected by your phone's own security: its screen lock, and the protection Android gives each app's private storage, which current phones encrypt. On Android 9 and later, DueTick's part of your Google backup is end-to-end encrypted with your screen lock (section 2). DueTick does not add its own extra encryption. No system is perfectly secure, so please keep your phone protected with a screen lock.

15. Children

DueTick collects no personal information from anyone, including children. The app is not made for children under 13. If a child has emailed us, tell us and we will delete the email.

16. Changes to this policy

If DueTick ever starts collecting information, this policy will change before the app does, and so will its Data safety section on Google Play. When we change this policy, we update the date at the top and mention significant changes in the app's release notes. You can ask us for any earlier version.
