Terms & Conditions

These terms apply to the VelocityLift app for mobile devices and the services that belong to it, operated by Lars Schneider, Tannenweg 6, 56075 Koblenz, Germany, velocityliftdev@gmail.com (the "Service Provider"; together the "Application"). By downloading or using the Application you agree to these terms.

Licence

The Service Provider grants you a limited, non-exclusive, non-transferable, revocable licence to install and use the Application on your mobile devices for personal use. You may not copy, distribute or modify the Application, or reverse engineer, decompile or disassemble it, except where applicable law expressly permits this. All rights in the Application, its code, design, names and logos remain with the Service Provider.

Age

You must be at least 16 years old to use the Application, or have the consent of a parent or guardian where your country requires it.

Measurements are estimates; train safely

VelocityLift estimates barbell velocity, range of motion, RPE, one-repetition maximums and related values from video. These values depend on camera position, lighting, calibration and tracking and can be inaccurate. They are a training aid, not medical advice and not a substitute for a coach, physician or physiotherapist. You are responsible for choosing loads you can lift safely, for using spotters and safety equipment, and for not operating your phone while lifting. Consult a physician before starting a training programme if you have health concerns.

Free version, VelocityLift Pro, Ad-Free and credits

• Every measurement is free. The free version shows ads while a newly recorded or imported set is analysed.
• VelocityLift Pro is offered as a monthly or annual subscription or as a one-time purchase and removes the ads and unlocks additional features described in the Application. VelocityLift Ad-Free is a one-time purchase that only removes the ads.
• Purchases are made through Google Play or the App Store. Prices, payment, taxes, renewal, cancellation and refunds are governed by the terms of that store. Subscriptions renew automatically at the end of each period unless you cancel them in the store's subscription management at least 24 hours before the period ends; cancelling ends the subscription at the end of the paid period. Statutory withdrawal rights for digital content are handled by the store.
• Credits can be earned by watching reward videos and spent on single Pro features or 24-hour passes. Credits are not money, have no cash value, cannot be bought, transferred or paid out, and may be lost when you uninstall the Application without an account. A per-use spend is refunded automatically if the feature could not be completed; passes are not refunded.
• The Service Provider may change features, prices of future purchases or the offer of credits. Features you have paid for remain available for the paid period, and for one-time purchases for as long as the Application is offered.

Optional account

You can create an optional account to back up and sync your training history. You are responsible for keeping your sign-in credentials confidential. You can delete your account and cloud data at any time in the Application.

Optional image contributions

If you consent to contribute image crops to improve plate detection, the separate contribution notice shown in the Application at the time of consent governs which rights you grant and how the images are used. You may only contribute recordings you made yourself and of which any other person shown has agreed. The Application has no other features for publishing or sharing content with other users.

Acceptable use

You may not use the Application in violation of applicable law, to infringe the rights of others, or to interfere with its services (for example by manipulating credits, purchases or the servers it uses). The Service Provider may suspend access to online features (account, sync, credits, contributions) in the case of a material breach; where the breach can be remedied, after written notice and 14 days to remedy it, and immediately in the case of unlawful use or abuse.

Third-party services

The Application uses services of third parties, whose own terms apply: Google Play Services, AdMob, Firebase (Authentication, Firestore, Analytics, Crashlytics, Performance Monitoring), RevenueCat and Cloudflare. Some functions (purchases, ads, account, sync) need an internet connection; data charges of your mobile provider are your responsibility. The analysis itself works offline.

Availability and updates

The Service Provider may update the Application and may stop supporting older versions or operating systems. You should install updates when offered. The Service Provider may discontinue the Application; in that case paid subscriptions end at the end of the current period and are not renewed.

Liability

The Service Provider is liable without limitation for intent and gross negligence, for injury to life, body or health, under the Product Liability Act and where a guarantee was given. For slight negligence the Service Provider is liable only for the breach of an essential contractual obligation (an obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose observance you may regularly rely), and limited to the foreseeable damage typical for this kind of contract. Otherwise liability for slight negligence is excluded. The Service Provider is not liable for loss of data that regular backups (for example the optional account sync or the data export) would have prevented. Your statutory rights as a consumer remain unaffected.

Governing law

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer with habitual residence in another country, the mandatory consumer protection provisions of that country remain applicable. The European Commission's online dispute resolution platform is no longer available; the Service Provider is neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board.

Severability and changes

If a provision of these terms is invalid, the remaining provisions remain in force. The Service Provider may update these terms for future versions of the Application; material changes will be announced in the Application. Previous versions are available on request.
