DueTick

Terms of Use for Android

Last updated: 3 November 2026

These terms are the agreement between you and OneMacStudio ("we", "us", "our"), a sole developer based in Tamil Nadu, India. OneMacStudio is the trading name of the individual developer named as the developer of DueTick on Google Play. These terms cover the DueTick Android app, its widget and DueTick Pro.

This page is for DueTick on Android. DueTick for iPhone has its own Terms of Use.

By downloading or using DueTick, you agree to these terms. If you do not agree, please do not use the app. If you are under 18, or under the age of adulthood where you live, a parent or guardian must agree to these terms for you.

Google Play has no standard licence for apps, so these terms are also your licence to use DueTick (section 7). Your use of Google Play itself is covered by Google's own terms.

We wrote these terms in plain English so that they can actually be read. The points in bold are the most important ones.

1. What DueTick does

DueTick is a personal tool for keeping track of dates that cost you something if you miss them. With it you can:

• add deadlines of three types: a Subscription (it renews and charges you unless you cancel), something that Expires (it runs out unless you renew it), or a One-time deadline (it happens once);
• see the day to act by, and how much time is left;
• get reminders;
• record what you did (for example Cancelled, Keeping, Renewed, Not renewing or Done), and take it back for a few seconds afterwards;
• put a question off to your next reminder day with Remind on, for example Remind on Sun 25 Oct;
• stop tracking a deadline and start it again later, or delete it;
• see your deadlines in a home screen widget;
• export a copy of your deadlines as a spreadsheet file.

2. What DueTick does not do

Please read this section carefully.

• It does not act for you. It cannot cancel a subscription, renew a policy or document, make a payment, or submit anything. You must do that yourself, directly with the company or authority concerned.
• It does not connect to your accounts. It is not connected to your bank, your cards, your Google Play subscriptions, your email or any company. It cannot see whether a charge was taken, a renewal went through, or a cancellation worked.
• It does not check what you enter. Every name, date, amount and choice comes from you. The app works out other dates, such as the next charge or the day to act by, from what you entered.
• It does not give advice. Nothing in DueTick is financial, legal, insurance, tax or other professional advice. The margins it keeps and the reminder options it offers are general settings, not a recommendation for your situation.
• It does not know the rules of the company you deal with. Companies set their own cancellation deadlines, billing times, notice periods and grace periods. They may charge earlier than you expect, bill in another time zone, or need notice well before the date. For example, many subscriptions renew automatically unless they are cancelled before the renewal, and some need notice days or weeks earlier. Always check the company's own terms.
• It is not part of your agreements with anyone. We are not a party to any agreement between you and the companies, insurers, authorities or anyone else your deadlines are about. Any question or dispute about a charge, cancellation, renewal, refund or penalty is between you and them.

3. Your part

DueTick is your tool, and you stay in charge of your deadlines. It works best when it has the right facts, and some things only you can do. So, when you use DueTick, you agree that it is your responsibility to:

• enter correct dates, amounts and details, and keep them up to date;
• check important dates against the real source, such as your bill, policy, contract, account page or official notice;
• act in time, and leave yourself a margin before the real deadline;
• keep notifications and Alarms & reminders allowed for DueTick, follow DueTick's Make sure reminders arrive steps for your phone, keep your phone switched on, charged and set to the correct date and time, and keep Android reasonably up to date;
• open DueTick from time to time, so that it can keep your reminders set (see "DueTick keeps 64 reminders set" in section 4), and not force-stop it;
• keep your phone's backup turned on, with a screen lock, if you want your deadlines kept safe when you change or lose your phone;
• keep another record, such as the company's own reminders or your calendar, for anything where missing the date would be serious, for example insurance, visa, passport, legal, tax or medical deadlines;
• keep your phone secure, because the names you enter can appear on your lock screen, in notifications and in the widget;
• make sure you are allowed to enter any information about other people, such as a family member's policy.

Please do not use DueTick for anything where a missed or late reminder could put anyone's health or safety at risk, such as the timing of medicine.

4. Known limits

DueTick is carefully built, but some limits come from Android, from your phone, from Google's services, or from how dates work. We would rather tell you now than have them surprise you later.

Reminders are not guaranteed. Reminders depend on Android and on your phone. Some phone makers' battery savers can delay or stop reminders even when DueTick has set them correctly. DueTick shows you how to allow them, but cannot promise that every reminder arrives. Please don't rely on DueTick as your only way to remember something important. A reminder can also be late, or never arrive, if for example notifications for DueTick are off or turned down, Alarms & reminders is off, Do Not Disturb holds it back, your phone is off or out of battery, or your phone's date or time is wrong. If DueTick is force-stopped, by you or by a cleaning or battery app, Android cancels its reminders until you open DueTick again. A reminder arrives on the day you choose, at your reminder time (9:00 in the morning unless you change it in Settings), by your phone's clock. If you have not answered, it comes again at 7:00 that evening, and at both times on your act-by day, when reminders also pop up on your screen. After your act-by day, DueTick sends no more reminders for that date: the deadline stays at the top of the app and is counted on the app icon, where your phone shows a count. A deadline you add on its act-by day gets only what is left of that day, and one you add after its act-by day gets no reminder for that date.

DueTick keeps 64 reminders set. DueTick keeps the nearest 64 reminders set at any time, and refreshes them whenever you open the app, and from time to time in the background when Android allows it. If you track many deadlines and do not open the app for a long time, later reminders may not be set yet. When this could happen, the last reminder set tells you to open DueTick.

After a restart. Android removes every app's alarms when your phone restarts. DueTick sets them again when your phone starts up. On some phones, this works only when DueTick is allowed to start on its own; Make sure reminders arrive shows how.

Dates, not times. Deadlines are saved as calendar days, not times. Companies bill in their own time zone, which no app can look up, so a charge date is shown as a date only. That is why DueTick keeps a margin: cancel 2 days before a charge, renew 2 days before something expires, and finish 1 day before something is due. If something that expires, or a one-time deadline, is closer than that, its margin is shortened to fit the time left.

Calculated dates can differ from real ones. For a subscription, DueTick works out each next charge from the date and the repeat you entered. The company may charge on a different day, for example in a short month, after changing its billing date, or after a failed payment. If that happens, update the date in DueTick.

Travelling. A day you save, say 12 October, stays 12 October wherever you are. Your phone decides when that day starts and ends, using the time zone it is in now. If you travel across time zones close to a deadline, the countdown can be off by up to a day.

What happens if you do not answer. If you do not answer about a subscription, DueTick assumes it renewed and moves on to the next date, because it cannot know whether you cancelled. Something that expires, and a one-time deadline, stay on the screen as overdue until you answer.

Backup, not sync. DueTick does not sync between phones: a deadline you add on one phone does not appear on another. Android's backup can keep a copy of your deadlines in your Google Account and bring it back on a new phone, or when you reinstall DueTick, with the same Google Account. Android and Google decide whether and when this happens: your phone's backup must be on, on Android 9 and later your phone needs a screen lock, and changes made since the last backup (usually up to a day) cannot be brought back. We cannot make, see or restore your backups.

The widget can be a little behind. The widget is redrawn when you change something in DueTick and when its words change, for example at midnight. Android can delay a redraw, especially while your phone is saving battery.

Amounts are notes. An amount is just what you typed. DueTick does not convert currencies, check anything against your bank, or include taxes and fees. A message such as "That's ₹649 you kept" is simply the amount you entered.

Your phone's clock. Counts such as "3 days left" are worked out from your phone's date, time and time zone. If those are wrong, the counts are wrong.

Gregorian calendar. Dates are shown in the Gregorian calendar (January to December).

Languages. DueTick is available in English, German, Japanese, French and Spanish.

Examples. The examples shown when you have no deadlines, such as "Netflix" or "Car insurance", are illustrations only. They are not real data, advice or endorsements.

Export is a copy, not a backup you can restore. The exported file is for your own records. DueTick cannot read it back in. It does not include reminder history, which reminders were delivered, your purchase, or deadlines you deleted.

Deleting is permanent. A deleted deadline cannot be recovered, by you or by us. "Stop tracking" keeps a deadline so that you can start it again.

5. Free use and DueTick Pro

• Free. DueTick is free to download. The free version lets you track up to 5 deadlines at a time. Deadlines you finished or stopped tracking do not count.
• Pro. DueTick Pro removes that limit. It is a one-time in-app purchase. It is not a subscription: it does not renew and does not expire. Pro changes how many deadlines you can add, and nothing else. It does not make reminders more reliable.
• Price. You pay the price shown in Google Play when you buy, in your local currency, including any taxes Google adds. Google takes the payment. Prices may change for future buyers.
• Where it is sold. DueTick Pro may not be sold in every country yet. Where it is not, the app says so, and the free version keeps working.
• Google Play handles payments, receipts and refunds, under Google Play's refund policies, together with any right to cancel a purchase that the law of your country gives you. For a short time after buying, you can ask Google Play for a refund yourself, and Google decides it. After that, email us. Any further refund is at our discretion, unless the law requires it, and is made through Google Play.
• Waiting payments. If your payment takes time to go through, as some UPI payments do, Pro unlocks once Google Play confirms it.
• Restoring. Pro belongs to the Google Account that bought it. On another Android phone, or after reinstalling, use the same Google Account in Google Play: Pro comes back by itself, or with Restore purchase.
• iPhone and Android are separate. DueTick Pro bought on an iPhone does not unlock DueTick on Android, and the other way round: Apple and Google keep their purchases apart.
• Family Library. Pro is not shared through Google Play Family Library.
• If a purchase is refunded or cancelled by Google, Pro turns off. Nothing is deleted: every deadline you already have keeps working, including its reminders, but you cannot add more until you are back under the free limit.
• Nothing you have already added is ever taken away because you did or did not buy Pro.

6. Your content and privacy

What you enter in DueTick is yours. We claim no rights over it, and we cannot see it. The DueTick Privacy Policy for Android explains how DueTick handles information. In short: no account, no server, no ads, no tracking and no analytics. Your deadlines stay on your phone and in your phone's own Google backup.

Because we hold no copy of your data, we cannot restore lost or deleted deadlines. Keep your phone's backup on, and use Export if you want your own copy.

7. Your licence to use DueTick

We give you a personal, non-exclusive, non-transferable and revocable licence to install and use DueTick on Android devices that you own or control, for your own use, under these terms.

You must not:

• copy, change, or make works based on DueTick, except as the law allows;
• reverse engineer, decompile or disassemble it, except where the law allows this despite this term;
• rent, lease, lend, sell, redistribute or sublicense it;
• get around the free limit or the purchase of DueTick Pro, or use a changed copy of DueTick;
• use it for anything unlawful, or in a way that could harm DueTick, us or anyone else.

Get DueTick only from Google Play. We do not publish it anywhere else. A copy from another place may have been changed, and we cannot support it.

DueTick, including its name, icon, design and code, belongs to us or our licensors and is protected by law. Some parts of it are open-source software, used under their own licences. These terms do not give you any right to use our name or logo.

Company and product names shown in DueTick as examples, such as Netflix or Amazon, belong to their owners. DueTick is not connected with, endorsed by, or sponsored by them. Android and Google Play are trademarks of Google LLC.

8. Changes to the app, and ending

We may update DueTick, change or remove features, or stop offering it. Some updates may be needed for the app to keep working, and future versions may need a newer version of Android. We do not promise to provide updates, or to keep DueTick available for any particular time. If we stop offering DueTick, we will try to tell you in advance where we reasonably can. Export lets you keep a copy of your deadlines.

You can stop using DueTick at any time by uninstalling it. Your licence ends automatically if you break these terms. Sections 2, 3, 4, 6 and 9 to 17 continue to apply after it ends.

9. No warranty

DueTick is provided "as is" and "as available". To the fullest extent the law allows, we make no promises or warranties of any kind, express or implied, including any implied warranties of merchantability, satisfactory quality, fitness for a particular purpose, accuracy and non-infringement. In particular, we do not promise that DueTick will be accurate, reliable, available, uninterrupted or error-free, that reminders will arrive, that backups will be made or restored, or that data will not be lost.

Some countries do not allow some warranties to be excluded. Where that applies to you, these exclusions apply only as far as your local law allows.

10. Limitation of liability

To the fullest extent the law allows, and whether a claim is based on contract, tort (including negligence), breach of statutory duty or anything else:

• We are not liable for any loss or damage that results from a missed, late or wrong deadline, date, amount or reminder. This includes subscription or renewal charges, late fees, penalties, fines, interest, lost refunds or return windows, lost or lapsed insurance cover, lost applications, registrations, benefits or opportunities, and the cost of putting any of these right.
• We are not liable for lost or damaged data, or for any indirect, incidental, special, consequential or punitive loss, or loss of profit, income, savings or goodwill, even if we were told it could happen.
• Our total liability to you, for all claims about DueTick together, is limited to the amount you actually paid for DueTick Pro. If you have not bought Pro, you have paid us nothing, and to the extent the law allows, our total liability is nothing.

Nothing in these terms limits or excludes any liability that the law does not allow to be limited or excluded, for example liability for death or personal injury caused by negligence, liability for fraud, or your statutory rights as a consumer.

11. Your responsibility to us

To the extent the law allows, you agree to cover us against any claims by others, and any resulting losses and reasonable costs (including legal costs), that arise from your breach of these terms or your unlawful use of DueTick.

12. Things outside our control

We are not responsible for any failure or delay caused by things we cannot reasonably control, for example changes to or outages of Android or Google's services (including Google Play and backup), your phone maker's software and settings (such as battery savers), internet or power failures, faults in your device, natural disasters, or actions of governments.

13. Google

DueTick is distributed through Google Play. These terms are between you and us only. Google is not a party to them, and is not responsible for DueTick, its content or its support. Purchases, payments and refunds are handled by Google Play under its own terms. When you use DueTick, you must also follow any other terms that apply to you, such as the Google Play Terms of Service.

14. Governing law and disputes

These terms are governed by the laws of India, and the courts of Tamil Nadu, India, have jurisdiction over any dispute about them. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring a claim in the courts where you live if your local law gives you that right.

Before starting any formal claim, please email us first at hello@onemacstudio.in, so that we can try to put things right. Most problems can be solved that way, quickly.

15. Changes to these terms

We may change these terms, for example when DueTick or the law changes. We will update the date at the top, and mention significant changes in the app's release notes. If you keep using DueTick after a change, you accept the new terms. If you do not agree with them, please stop using DueTick and uninstall it.

16. General

• If part of these terms is invalid, that part is limited or removed only as much as needed, and the rest stays in force.
• If we do not enforce a right straight away, we have not given it up.
• Transfer. You may not transfer your rights under these terms. We may transfer ours to anyone who takes over DueTick, as long as that does not reduce your rights under these terms.
• Whole agreement. These terms and the DueTick Privacy Policy for Android are the whole agreement between you and us about DueTick.
• Language. These terms are written in English. If they are ever translated, the English version applies where the law allows.
