By purchasing, accessing, or using Cycle Tracker (the "App"), you agree to be bound by these Terms of Use. If you do not agree, do not use the App.
These terms apply to all users of the App, including the hosted version at cycle-tracker.com.
Cycle Tracker is designed to help you log and track personal health data for your own reference. The App does not:
• Provide medical diagnoses or treatment recommendations
• Replace the advice of a doctor, midwife, or licensed healthcare provider
• Guarantee the accuracy of cycle predictions or health insights
• Constitute a fertility planning tool or contraceptive method
The App's cycle predictions are simple arithmetic based on the dates you enter. They are not a clinical assessment, and they say nothing reliable about when you are or are not fertile. Do not use Cycle Tracker — including its basal temperature or cycle phase features — to avoid or achieve pregnancy. Fertility awareness methods require proper training and clinical support.
Always seek professional medical advice for health concerns, fertility planning, or any medical decisions. Do not delay seeking medical care based on information from this App.
You must be at least 16 years old to purchase Cycle Tracker, or the minimum age of digital consent in your country if that age is higher. If you are under that age, a parent or guardian must make the purchase and set up the App for you.
You are responsible for ensuring that any payment method you use is one you are authorised to use.
We do not collect, store, or receive the health data you log. Everything you enter is stored in:
• Your browser's local storage — on your device only
• Your own Google Sheet — in your personal Google account, via a script you deploy yourself
Your entries travel directly from your device to your own Google Apps Script deployment. They never pass through our servers, and we have no ability to read them.
To be precise about what does reach us: the App's files are served from our website, and when you unlock the App your licence key is sent to our verification service to confirm it is valid. That request contains the key only — never your health data. Ordinary server logs may record technical details such as IP address and timestamp, as is standard for any website.
The App also loads fonts from Google's font service, and your data is stored with Google. Their handling of that data is governed by Google's privacy policy, not ours. You are responsible for the security of your Google account and anything stored in it. We recommend enabling two-factor authentication on it.
You can delete your data at any time by deleting your Google Sheet and clearing your browser storage for the App.
Your purchase grants you a personal, non-transferable licence to use the App. You may use it on as many of your own devices as you like. You may not:
• Resell, sublicense, or redistribute the App or its source code
• Share your licence key with others or publish it
• Use the App to provide commercial tracking services to third parties
• Copy the App for redistribution
We may deactivate a licence key that has been publicly shared or is being used in a way these terms prohibit. Where we do so in error, we will restore it.
Cycle Tracker is sold as a digital product through Gumroad, who act as the merchant of record for your purchase. Their checkout terms apply alongside these terms.
Because access is granted immediately on purchase, we do not offer refunds as a matter of course. This does not affect any statutory rights you have under the consumer law of your own country, which in some places includes a cancellation period for digital purchases. Nothing in these terms limits rights that cannot be limited by agreement.
If the App does not work as described and we cannot resolve it for you, contact us and we will refund you. We would rather do that than have you stuck with something you can't use. Try the live demo before buying to be sure it suits you.
Your licence has no expiry date and there is no subscription. However, the App is served from our website and its licence check depends on our verification service, so continued access depends on those staying online. We do not guarantee uninterrupted or error-free access, and we may update or change features at any time.
If we ever decide to discontinue the hosted App, we will give existing purchasers at least 90 days' notice by email and make a self-hosted copy available so you can keep using it. Your logged data is unaffected either way — it lives in your own Google Sheet and remains yours whatever happens to us.
The App is provided "as is", without warranties of any kind beyond those that cannot lawfully be excluded.
To the fullest extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from:
• Your use of or inability to use the App
• Any reliance on data, predictions, or information provided by the App
• Data loss, service interruptions, or technical errors
• Decisions made based on App content, including health or fertility decisions
• Any third-party services connected to the App (e.g. Google Sheets, Gumroad)
Where liability cannot be excluded, it is limited to the amount you paid for the App. Nothing in these terms excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.
We may update these terms from time to time. The date at the top of this page shows when they last changed. If a change materially reduces your rights, we will notify existing purchasers by email. Continuing to use the App after a change means you accept the updated terms.
These terms are governed by the laws of the province of Ontario, Canada, and the courts of Ontario have jurisdiction over any disputes.
If you are a consumer resident elsewhere, this does not deprive you of the protection of mandatory consumer law in your own country, or of the right to bring proceedings there where local law gives you that right.
