Terms of Service
Last updated: September 25, 2026
These Terms of Service ("Terms") govern your use of Between Contractions, a free contraction timer for expecting parents available as a browser-based Web App and native apps for iPhone, iPad, Mac, and Android (together, the "Service"). By downloading, opening, or otherwise using the Service, you agree to these Terms. If you don't agree, please don't use the Service.
1. What Between Contractions Is
Between Contractions helps you time contractions, view your contraction history, and get an alert based on the widely-used 5-1-1 rule (contractions roughly 5 minutes apart, lasting about 1 minute, for 1 hour). The core timer is free and ad-free, and does not require an account.
2. Local Data and Optional Partner Sync
Without Partner Sync, your contraction history is stored locally on your device, including in local browser storage when you use the Web App. Partner Sync is an optional service that sends one selected pregnancy's timer and history through the Between Contractions relay so invited devices can stay synchronized. See our Privacy Policy for the data involved, retention limits, and deletion choices.
3. Partner Sync Subscription
Creating a Partner Sync group requires the monthly auto-renewable subscription shown by Apple or Google at checkout. Only the group creator subscribes; invited devices join free with the six-character code. Payment, renewal, billing recovery, cancellation, and refund handling are provided by the store where you purchased. You can manage or cancel the subscription in that store's account settings. Ending a shared group does not itself cancel the store subscription, and canceling renewal normally leaves access active through the paid period unless the store revokes or refunds it earlier.
4. Acceptable Use
You agree to use the Service only for its intended purpose of personal contraction tracking, and not to misuse it, attempt to reverse engineer it beyond what applicable law permits, interfere with another group, share invitation codes publicly, or use it in any way that could damage, disable, or impair the Service for other users.
5. Intellectual Property
The Between Contractions name, logo, design, and underlying source code are the property of the developer and are protected by applicable intellectual property laws. These Terms don't grant you any rights to use the Between Contractions name or branding outside of using the App as intended.
6. Disclaimer of Warranties
The Service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We don't guarantee that timing, calculations, alerts, or synchronization will be error-free, uninterrupted, or perfectly accurate.
7. Limitation of Liability
To the fullest extent permitted by law, the developer of Between Contractions will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data or health outcomes, arising from or related to your use of, or inability to use, the Service. Nothing in these Terms limits liability that cannot be limited under applicable law.
8. Changes to These Terms
We may update these Terms from time to time, for example as the App gains new features. When we do, we'll update the "Last updated" date above. Continuing to use the Service after changes take effect means you accept the revised Terms.
