Export your fasting data as CSV (because it's yours)

Why data ownership matters for fasting logs, what FastHQ's CSV export contains, and how one-row-per-fast with ISO 8601 timestamps lets you analyze your own history.

Updated #data#csv#privacy#quantified-self

Your fasting log is a record of something you did with your own body. FastHQ’s position is simple: that record is yours, and you should be able to take it anywhere. So every fast you log can be exported as a CSV — one row per fast, clean timestamps, no lock-in.

What’s in the export

The CSV is deliberately boring and complete. One row per fast, with:

  • start time and end time — ISO 8601 timestamps, so any spreadsheet or script parses them correctly
  • protocol — 16:8, 18:6, OMAD, 24h, or custom
  • target hours and actual duration
  • result — complete or broken

That’s it. No proprietary format, no export that’s really a screenshot. A file you can open in any spreadsheet.

Why this matters

For anyone who takes a quantified-self approach, the log is the point. Owning it as plain data means you can:

  • chart your real fasting history over months,
  • correlate it with anything else you track,
  • keep a backup that doesn’t depend on us, and
  • leave whenever you want and take everything with you.

The last one matters most. Export is the opposite of lock-in. An app confident in its product doesn’t need to trap your data to keep you.

Honest data, including the bad fasts

FastHQ logs every fast as you actually did it — including the ones you ended early, marked plainly as “broken.” We don’t quietly drop the fasts that would spoil a streak, because there are no streaks, and because honest data is more useful than clean data. Your CSV reflects what really happened, not a tidied highlight reel.

Privacy, briefly

Your fasting log lives in your account with row-level security — only you can read it. We never sell or share it. The CSV just makes the ownership explicit: it was always yours; export hands you the file.
