Terms of Use

Last updated: 14 September 2026

These Terms of Use ("Terms") are an agreement between you and BitCraftery ("we," "our," or "us") — a trading name of a sole trader based in the United Kingdom, not a registered company — governing your use of the Weighly app. By downloading or using Weighly, you agree to these Terms. If you do not agree, please do not use the app.

The App

  • Weighly is a personal weight, calorie, and workout tracking app with no adverts. Adding new entries (weight logs, progress photos, goals, food and workouts) requires the Weighly Premium subscription described below; anything you have already logged stays viewable without one.
  • We grant you a personal, non-exclusive, non-transferable, revocable licence to use Weighly on Apple-branded devices or Android devices that you own or control, in line with the App Store Terms of Service or the Google Play Terms of Service respectively.
  • Signing in is required to use the app — with Apple on iOS, and with Apple or Google on Android. You are responsible for keeping the account you sign in with secure.

Weighly Premium

  • Weighly Premium is an auto-renewing subscription, billed monthly or yearly, that unlocks adding new entries together with calorie tracking, workout insights, and photo comparisons. Any price shown on our website is the United Kingdom price; the price that applies to you is the one shown in the app and in the App Store, in your own currency, before you subscribe.
  • New subscribers may be offered a free trial: one month on the annual plan, one week on the monthly plan. The App Store shows whether you are eligible, and for how long, before you confirm. Any unused portion of a free trial is forfeited when your paid subscription starts.
  • Payment is charged to your Apple ID account at confirmation of purchase (or when a free trial ends). The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; the renewal charge is applied within 24 hours before the period ends.
  • You can manage or cancel your subscription at any time in your App Store account settings. Cancelling stops future renewals; premium features stay unlocked until the end of the period you have paid for.
  • Purchases are processed by Apple, and refunds are handled by Apple under the App Store's terms.

Not Medical Advice

Weighly is a self-tracking tool to help you record your weight, food, workouts, and goals. It is not a medical device and does not provide medical, nutritional, or health advice. Do not rely on it to diagnose, treat, or manage any health condition. Always consult a qualified healthcare professional before making decisions about your weight, diet, or health, and seek professional support if you have any concerns about disordered eating.

Acceptable Use

  • You must be at least 13 years old to use Weighly.
  • You agree to use the app lawfully and not to misuse, disrupt, reverse engineer, or attempt to gain unauthorised access to it or our systems.
  • You agree not to submit unlawful, infringing, or harmful content through Help and Feedback.

Your Content

You keep ownership of the feedback and images you send us. By submitting them, you grant us a licence to use them to provide support and improve the app, and you confirm you have the right to share what you submit.

Your Data

Our handling of your information is described in our Privacy Policy. Your weight entries, goals, photos, and food diary are stored on your device; you are responsible for your own device backups, as we do not back up on-device data. A workout you are recording, and a finished workout that has not been saved to Apple Health yet, are held in a file on your device until you save or discard it. A workout that has been saved to Apple Health belongs to the Health app, so deleting Weighly does not remove it. Deleting the app or your account removes data as described in the Privacy Policy.

Apple Health

On iOS, with your permission, Weighly can read data from Apple Health (such as workouts, energy burned, heart rate, steps, workout distances, and the routes of outdoor workouts) to show your activity, personalise your calorie targets, and draw your route on a workout video you share. With your permission, Weighly also saves the workouts you record in the app to Apple Health, with the calories burned and, where they were measured, the distance covered and the route. Weighly asks for reading and writing in the same Health sheet, so you answer once. If you connected Health in an earlier version, iOS asks you only about what is new: saving the workouts you record, and reading outdoor workout routes. This data is processed on your device only, is never used for advertising or marketing, and is never sold or shared. See the Privacy Policy for details. Figures derived from Health data are estimates: they are not medical measurements, and the Not Medical Advice section applies to them in full. You can delete a workout Weighly saved from inside the app, which also asks Apple Health to remove the energy, distance, and route saved with it. Workouts saved to Apple Health belong to the Health app, so deleting Weighly does not remove them. You can withdraw Weighly's Health access at any time in the Health app or iOS Settings.

Workouts You Record

On iOS, weighly can record a workout on your phone. If the activity is outdoors and covers ground, Weighly uses your location while the workout is running to measure the route, distance, and pace. Indoor and stationary activities do not use location.

  • Calories are an estimate: the figure is worked out from the activity, your weight (or a typical weight, if you have not logged one yet), your GPS speed outdoors, and the effort you report. It is not a measurement, and a watch or chest strap is more accurate.
  • Distance and pace come from GPS: their accuracy depends on the signal your phone receives.
  • These are not medical measurements: the Not Medical Advice section applies to them in full.
  • Location is optional: if you do not allow it, the workout still records, without a route, distance, or pace. A distance goal needs location turned on, and precise location, or there is nothing to measure it with.
  • Recording uses battery: for an outdoor workout, location and background activity keep running until you end the workout, which can noticeably reduce battery life.
  • Stay aware of your surroundings: recording a workout should never distract you from traffic, your route, or the law where you are.

Intellectual Property

Weighly, including its name, design, features, and code, belongs to BitCraftery and is protected by law. You may not copy, modify, distribute, or create derivative works from any part of the app.

Disclaimers

Weighly is provided "as is" and "as available," without warranties of any kind, whether express or implied.

Limitation of Liability

To the fullest extent permitted by law, BitCraftery is not liable for any indirect or consequential loss, or for any loss of data, arising from your use of the app. Nothing in these Terms limits any liability that cannot be excluded under applicable law, including your statutory rights as a consumer.

Governing Law

These Terms are governed by the laws of England and Wales. This does not affect any mandatory consumer-protection rights you have in your country of residence.

Changes to These Terms

We may update these Terms from time to time. We will revise the date above and, for significant changes, let you know within the app. Continued use of Weighly after changes take effect means you accept the updated Terms.
