Who can use Precursor
Precursor is not directed at children under 13, and you must be at least 13 years old to use it. If you are under 18, use Precursor only with a parent or guardian's permission. Permissions on managed child accounts are governed by Apple's Family Sharing rules or by Google's Family Link rules, not by us.
Your license
We grant you a personal, non-transferable, non-exclusive license to use Precursor on any Apple or Android device that you own or control. For copies obtained through the App Store, this license is also subject to the App Store Usage Rules in Apple's Media Services Terms and Conditions; for copies obtained through Google Play, it is also subject to the Google Play Terms of Service. You may not sell, rent, sublicense, or redistribute the app, and you may not copy, modify, reverse engineer, or attempt to extract the source code of the app except to the limited extent the law allows. The app, its design, and the Precursor name and marks remain the property of Precursor Labs LLC; these Terms give you a license, not ownership.
Free and paid features
Precursor is free to use, with a full core experience at no cost. An optional upgrade, Precursor+, unlocks additional features and is available as a monthly or yearly subscription or as a one-time Lifetime purchase.
- Payments. All purchases are processed by Apple (through your Apple ID) or by Google Play (through your Google account). We never receive or store your payment details; a record of what you unlocked is validated for us by RevenueCat, as described in the Privacy Policy. Current prices are shown in the app before you buy and may vary by region.
- Auto-renewing subscriptions. Monthly and yearly Precursor+ subscriptions renew automatically. Your Apple ID or Google account is charged at confirmation of purchase, and the subscription renews for the same period at the then-current price unless you turn off auto-renew at least 24 hours before the current period ends. You can manage or cancel a subscription any time in your Apple ID settings or in Google Play's subscription settings; cancelling stops the next renewal and does not refund the current period.
- Free trials. If a free trial is offered, it converts to a paid subscription unless you turn off auto-renew before the trial ends. Any unused portion of a trial is forfeited when you buy a subscription.
- Lifetime. The Lifetime option is a one-time purchase, not a subscription, and does not auto-renew.
- Refunds. Purchases are handled by Apple or Google Play, and refund requests are managed by the store you bought through, under its terms. We cannot issue refunds directly.
What Precursor is, and is not
Precursor is a self-management tool that helps you set your own limits on how you use your apps. It is not medical, psychological, or therapeutic advice, diagnosis, or treatment, and it is not a substitute for professional care. You are responsible for the limits you set and for your own use of your device.
How the app works, and its limits
On iPhone and iPad, Precursor is built on Apple's Screen Time technology (the Family Controls, Device Activity, and Managed Settings frameworks); on Android, it is built on the system's usage-access and accessibility services. Because enforcement depends on the operating system, the permissions you grant, and your device's behavior, Precursor cannot guarantee that limits will always apply exactly, on time, or without interruption, and Apple's or Google's own updates may affect how limits work. The app is provided "as is" and "as available", without warranties of any kind to the fullest extent permitted by law. Deleting Precursor removes all of its limits from your device; the optional passcode protects your settings from impulsive changes, not your ability to leave.
Acceptable use
Use Precursor only for your own lawful, personal purposes. Do not use it to interfere with or gain unauthorized access to any system, to work around Apple's or Google's rules, or in any way that could harm Precursor, Apple, Google, or other people.
Privacy
Our Privacy Policy explains what the app does and does not collect. In short: there are no accounts, we cannot see which apps you limit, and your data stays on your phone unless you explicitly choose to share it.
Third-party services
A few optional surfaces are run by others: the in-app feedback board is hosted by Featurebase, and this site may link to other sites. Those services have their own terms and policies, and we are not responsible for their content or practices.
Apple's and Google's role
Apple and Google are not parties to these Terms and are not responsible for Precursor. Where you obtain the app through the App Store, Apple's standard Licensed Application End User License Agreement also applies to your use of the app, and to the extent these Terms conflict with it on the points it covers, that agreement governs. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them. Where you obtain the app through Google Play, the Google Play Terms of Service also apply to your download and use of the app.
Limitation of liability
To the fullest extent permitted by law, Precursor Labs will not be liable for any indirect, incidental, special, or consequential damages, or for any loss arising from your use of, or inability to use, the app. To the same extent, our total liability for all claims relating to the app will not exceed the greater of the amount you paid Precursor Labs in the twelve months before the claim arose or fifty US dollars ($50). Nothing in these Terms limits any rights you have that cannot be limited under the law that applies to you.
Your responsibility for misuse
If your breach of these Terms or unlawful use of Precursor causes a claim against Precursor Labs, you agree to cover the resulting losses and reasonable costs to the extent the law allows.
Termination
You can stop using Precursor at any time; deleting the app ends your license and removes all of its limits from your device. We may suspend or end your license if you materially breach these Terms. Sections that by their nature should continue (including the disclaimers, limitation of liability, and governing law) survive termination. Ending the license does not by itself refund purchases; refunds stay governed by the rules of the store you bought through.
Changes
We may update these Terms as the app changes. When we do, we will update the date above. Continuing to use Precursor after a change means you accept the updated Terms.
Governing law
These Terms are governed by the laws of the State of California, United States, without regard to its conflict-of-laws rules, except where the law that applies to you as a consumer provides otherwise. Any dispute that is not subject to a consumer-protection rule giving you a different forum will be resolved in the state or federal courts located in California.
About these Terms
These Terms, together with the Privacy Policy, Apple's standard EULA where it applies, and the Google Play Terms of Service where they apply, are the entire agreement between you and Precursor Labs about the app. If any part of these Terms is found unenforceable, the rest remains in effect, and not enforcing a provision is not a waiver of it. You may not assign these Terms; we may assign them as part of a merger, acquisition, or sale of assets.
