Privacy policy
This app stores timer settings and session logs (time, duration, memo) locally in IndexedDB on your device. This data is not sent to external servers.
If Google AdSense is used, cookies and similar technologies may be used to show relevant ads. See the link below for details.
Google Ads – Policies
Spacing is kept between the fixed ad area at the bottom and main controls to reduce accidental clicks. Depending on AdSense settings, additional automatic ads may appear elsewhere.
Contact form data
If you contact us via Google Form, we may collect the items shown in the form (such as email address, name, subject, and message body) to respond to your inquiry.
Your submission is processed and stored through Google services. Do not send passwords, payment details, or other sensitive information in the form.
Inquiry data is retained only as needed for response and record-keeping, then deleted when no longer necessary.
Backup & export
You can export session logs as a JSON file saved on your device. The site operator does not receive that file. Keep exported files secure if they contain personal notes.
Disclaimer
This service is provided “as is” for personal productivity. It is not legal, tax, or labor-compliance advice. The operator is not liable for loss or disputes arising from use of the timer or stored data. For formal record-keeping obligations, consult a qualified professional.
