Delete your data
This section covers Precursor, made by Precursor Labs. Almost everything Precursor knows lives on your phone: your limits, usage, and Insights are stored on your device only, and deleting the app deletes them.
The few things that can reach us (bug reports, opt-in statistics) are tied to a random install identifier, never to your name or an account. To erase them, open Precursor and choose Settings, then Delete my data. That removes every bug report and statistic tied to your install from our systems and destroys the identifier itself, so nothing sent before can ever be connected to anything after. Bug reports also age off on their own within 90 days.
Two things sit outside that button. Purchase records are held by Apple, Google Play, and RevenueCat (our purchase processor) under their own retention rules; they are not ours to delete. And if you joined the beta list with your email, reply to any of our emails or write to us and we delete it.
Already deleted the app, or prefer email? Write to support@precursorlabs.info and we will take care of it for you.
Common questions
Apple's limits are a single daily budget: once it runs out, the app is gone for the rest of the day. Precursor gives each app a small allowance that resets every hour. Use up your five minutes and the app is blocked, then at the top of the next hour you get five fresh minutes. It is a gentler rhythm than one hard cutoff a day.
An iPhone or iPad running iOS 17 or later. Precursor is built on Apple's Screen Time technology, so it asks for Screen Time permission the first time you set a limit. An Android version is in testing and coming soon to Google Play; join the early-access list on the homepage and we will let you know the moment it is out.
About five minutes per hour is the reliable floor. iOS measures usage in coarse samples, so allowances below roughly five minutes behave inconsistently and can block right at the hour boundary. Five minutes and up is dependable.
Usage is measured by iOS, not by Precursor, and for some apps that includes audio or video that keeps playing in the background or in picture in picture. If a music or video app keeps running after you leave it, iOS still counts that as usage. There is no setting to change this, so we would rather tell you plainly than have it look like a glitch.
The passcode is optional. It protects your limit settings from an impulsive change in the moment, not your ability to leave. If you forget it, there is a built in reset you can start and confirm after a short wait, and deleting the app removes every limit immediately.
All of its limits come off your device right away, and your limits, history, and Insights go with the app; they only ever lived on your device. If you had turned on shared statistics or sent a bug report, those few items follow the privacy policy instead: delete statistics from Settings before removing the app, or email us and we will clear them. Bug reports age off our systems within 90 days regardless.
No. When you pick apps, iOS hands us anonymous tokens, never names or identities. We could not tell you which apps you limit even if you asked. Your choices, limits, and usage stay on your phone.
The core app is free, with a full experience at no cost. An optional upgrade, Precursor+, adds more features as a monthly or yearly subscription or a one time Lifetime purchase. All purchases are handled by Apple or Google Play.
That second screen is your iPhone's own Screen Time App Limit, not Precursor. If you set an App Limit in Settings on the same app you gave Precursor, iOS shows its own block, and that one can be tapped away with the “Ask For More Time” button. Precursor cannot see or change Apple's screen. The simplest fix is to turn off Apple's App Limits altogether and let Precursor do the limiting: open Settings, then Screen Time, then App Limits, and switch App Limits off (or at least remove the limit on any app you also gave Precursor). While you are there, tap Lock Screen Time Settings and set a passcode so limits cannot be switched off on impulse.
Report a bug
The fastest route is inside the app: Settings, then Report a bug. That sends your note along with a technical log, timestamps and limit events only, never personal information or the names of the apps you limit.
No app handy? Email works too. A device model and OS version help us find it faster.
