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.

How to use

All features run in your browser; logs stay on this device only.

Timer

  • Choose a preset or open Custom to set minutes and seconds, then Apply.
  • Start runs the countdown. Pause holds the remaining time; Reset returns to the selected duration.
  • When time is up, a short sound plays and a toast appears.

Log tab

  • Completed sessions are listed under Log, grouped by date.
  • Tap a date heading to expand or collapse that day.
  • Use Edit to change a memo, or Delete to remove an entry (with confirmation).
  • Export saves logs as JSON for backup; Import restores a backup and replaces all logs on this device (with confirmation).

Ways to use

  • Focus blocks of any length—e.g. 25 minutes work / 5 minutes break—using Custom.
  • Add short memos to logs to remember what each session was for.
  • After the first visit, the app can work offline as a PWA (install varies by browser).
  • Examples: 30 seconds for speech openings or drills, 1 minute for plank holds, 3 minutes for ramen or tea—built-in presets match common routines.

Data & privacy

Timer settings and logs are stored in IndexedDB in this browser profile. They are not uploaded to a server.

To wipe everything, clear site data for this site in your browser settings, or delete entries one by one in the Log tab.

If saving fails, storage may be full, blocked, or unavailable (e.g. private browsing). Export regularly if you need a backup.

About this site

TightTimeLog runs in your browser and keeps timer sessions and optional memos on your device.

Background

This project is built and maintained as a personal, solo effort—not a company product.

The idea is simple: pair a timer with a short memo about what you were doing. That combo is handy for everyday training, meal timing and pacing, and other small routines you want to glance back at.

Settings

Haptic feedback

Adds a short vibration when you tap Start, Pause, or Reset on supported devices.

Depending on your device, browser, and system settings (silent mode, battery saver, accessibility, or vibration off), feedback may not occur even when enabled.
