FAQ
- UUID v1 / v7?
- This page is v4 (random). Time-based versions are not here.
- Collision risk?
- v4 collision is not a practical worry for normal apps.
- Do you store what I type?
- Browser tools stay in this tab. Refreshing the page clears the form. Nothing is saved to a Pulse account.
- Is this free?
- Yes. Pulse stays free because of advertising. Ads may appear when you copy, download, or run the main action.
