Privacy Policy
Last updated: 19 February 2026
Overview
Singlio is a focus and distraction tracking app built by First Principles Studio Ltd (Company No. 16962497). We take your privacy seriously. In short: your data stays on your device. We don't collect it, store it, or share it.
Data Storage
All data you create in Singlio — including focus sessions, tasks, scores, and preferences — is stored locally on your device using on-device storage. No data is transmitted to our servers or any third party.
Data We Collect
We do not collect any personal data ourselves. Singlio does not require an account, login, or internet connection to function. We do not use analytics, tracking pixels, or any form of telemetry. Any data collected by third-party services is governed by their own privacy policies.
Third-Party Services
Singlio may display advertisements through Google AdMob in the free version of the app. AdMob may collect device identifiers and usage data in accordance with Google's Privacy Policy. We do not have access to this data. No other third-party services are used.
Notifications
If you enable task reminders, Singlio schedules local notifications on your device. These are processed entirely on-device and no notification data is sent externally.
Data Deletion
You can delete all your data at any time from the "You" tab within the app. Uninstalling the app also removes all stored data from your device.
Children's Privacy
Singlio is not directed at children under 13. We do not knowingly collect any data from children.
Changes to This Policy
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date.
Not Medical Advice
Singlio is a productivity and self-improvement tool and is not intended to provide medical, psychological, or diagnostic advice. We are not medical professionals. If you have concerns about your mental health, attention, or well-being, please consult a qualified healthcare professional.
Jurisdiction
This policy is governed by the laws of England and Wales.
