This Privacy Policy forms part of and must be read in conjunction with the Interval HIIT Timer app Terms and Conditions. We reserve the right to update this Privacy Policy at any time. Any changes will be effective immediately upon publication within the app or on the app store listing.
Interval HIIT Timer (“we”, “us”, “our”) is developed and operated by a solo independent developer based in Manchester, United Kingdom. We respect your privacy and are committed to protecting it in compliance with applicable data protection laws, including the UK GDPR, EU GDPR, and relevant Apple App Store and Google Play Developer Program policies.
If you have any questions or concerns about this Privacy Policy or our data practices, you can contact us using the details provided at the end of this document.
This Privacy Policy applies to all information collected through:
The Interval HIIT Timer mobile application (iOS and Android)
Any related services, features, support communications, or app updates
By downloading or using the app, you agree to the collection and use of information in accordance with this Privacy Policy.
We do not require user accounts and do not collect personally identifiable information (PII) such as your name, email address, phone number, or precise location in order to use the app.
We may collect limited, non-identifiable, aggregated usage data to help improve the app, such as:
App interactions (e.g. buttons pressed, features enabled/disabled)
Timer settings and feature usage patterns
App stability data (crash logs, performance metrics)
Approximate location data (country-level only)
This data:
Is anonymised and aggregated
Cannot be used to identify you personally
Is used solely to improve functionality, performance, and user experience
By default, your workout configurations, presets, and workout history are stored locally on your device using secure local storage. This data never leaves your device unless you explicitly enable optional cloud-related features in future versions of the app.
We use the limited data we collect for the following purposes:
To operate and maintain the app
To understand feature usage and improve user experience
To identify and fix bugs or performance issues
To comply with legal obligations
All processing is carried out based on legitimate interests, user consent where required, or legal necessity.
We may use trusted third-party analytics services (such as Google Firebase or Google Analytics for Firebase) to collect anonymised usage statistics.
These services may collect:
App usage frequency
Feature engagement
Device type and operating system
Country-level location
All analytics data:
Is anonymised
Is not linked to your identity
Is processed in accordance with the provider’s privacy policies
You can review Google’s Privacy Policy here:
If advertising is introduced (now or in future versions), ads will:
Comply with Google Play and Apple App Store advertising policies
Not be based on sensitive personal data
Not knowingly target children
Where required, consent mechanisms will be provided.
We do not sell your data.
We may share limited information only in the following situations:
Legal Compliance: If required by law, regulation, or legal process
Safety & Rights Protection: To investigate or prevent misuse, fraud, or harm
Service Providers: With trusted third parties who help operate the app (e.g. analytics, crash reporting), under strict confidentiality obligations
We retain anonymised analytics data only for as long as necessary to fulfil the purposes described in this policy.
Local workout data remains on your device unless you delete the app or clear app data.
Depending on your location, you may have rights under data protection laws, including:
The right to access information about data processing
The right to request deletion of applicable data
The right to object to certain processing activities
As we do not collect identifiable personal data by default, most of these rights do not apply in a traditional sense. However, you may contact us at any time with privacy-related questions.
Interval HIIT Timer is not intended for children under the age of 13 (or 16 where applicable by local law).
We do not knowingly collect personal data from children. If you believe that a child has provided personal information, please contact us and we will take appropriate action.
We use reasonable administrative and technical safeguards to protect any data processed. However, no method of electronic transmission or storage is 100% secure, and absolute security cannot be guaranteed.
We may update this Privacy Policy from time to time. The updated version will be indicated by a revised “Last updated” date and will be effective immediately upon publication.
We encourage you to review this policy periodically.
