Flowglass is a focus timer with an optional game layer (XP, levels, skills, streaks and quests). The timers, XP, levels, skills, streaks, the daily quest and the last 7 days of statistics are free. Optional extras are planned as a low-cost monthly “Pro” subscription.

Flowglass works without an account and then stores your data only on your device — which means we cannot recover it for you if you clear your browser data, change devices or uninstall the app. Use Settings → Privacy & data → Export my data to keep a copy, or sign in (optional) to back it up and sync it. You are responsible for keeping access to the email address you sign in with. We may delete accounts that are used to abuse the service.

Pro is not for sale on the website. The “Founding Pro — I’m interested” button only records anonymous interest; it is not an order and creates no obligation for you or for us.

If Pro becomes available as an in-app purchase, it will be an auto-renewing monthly subscription that unlocks the listed extras on the store account you subscribe with. The price is always shown before you confirm. It renews each month at the same price until you cancel; you can cancel anytime in your App Store or Google Play subscription settings, at least 24 hours before the renewal date, and keep Pro until the end of the period you paid for. If we ever change the price, the store will tell you in advance and ask for your consent where required. Payments are processed by Apple or Google under their terms; see the Refund Policy for refunds.

Flowglass is a productivity tool, not a medical device or treatment. Articles about focus, studying or ADHD are general information and are not medical advice. Talk to a qualified professional about health concerns.

The Flowglass name, interface, illustrations, emblems and text belong to the operator of Flowglass. Third-party components are used under their own licenses (see Legal notice & credits).

Flowglass is provided “as is” and “as available”. To the extent permitted by law, we make no warranties that it will be uninterrupted or error-free, and we are not liable for indirect or consequential losses, or for loss of locally stored data. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer.

We may update Flowglass and these terms. If the terms change materially we will update the date at the top of this page. You can stop using Flowglass at any time; deleting your data is described in the Privacy Policy.
