What you’ll see

  • Current rhythm — the shape of a recent stretch of the log.
  • Whole journey — how the recorded pattern shifted month by month.
  • Share card — one image you can keep, drawn in this tab.
Example rhythm ribbon — synthetic data, not a real family’s log Ninety slim day-columns run left to right, oldest first. Each column is one day, from 06:00 at the top to 06:00 the next morning at the bottom. In the earliest columns four short hatched nap bands sit through the daytime and the night is broken into three solid bands, the longest about four hours. Moving right, the naps merge into a single midday island and the night bands join into one solid band of about nine hours. Small teal triangles mark feed starts: about nine a day at the left, about five at the right, and none overnight by the end. Every value is invented for this example. 06:00 12:00 18:00 00:00 06:00 EXAMPLE — SYNTHETIC DATA EARLIEST DAYS MOST RECENT DAYS
  • Logged night sleep — solid band
  • Logged nap sleep — hatched band
  • Feed start — triangle
Example report — synthetic data, not a real family’s log. In this example, four naps settle into one and the longest logged night stretch grows from about 4 hours to about 9 — roughly 2.2× longer. Each column is one day, 06:00 at the top down to 06:00 the next morning. Times would be shown exactly as recorded in your own export.

How it works

  1. Export your log from Huckleberry. You get a .csv file, and that is the file to choose here. How to export your Huckleberry data.
  2. Choose the file here. Your browser reads it on this device, in a background thread. Only this tab ever sees the data.
  3. See your rhythm. The current chapter, the whole journey, and a share card you control.

Privacy details

Private by design. Your CSV is read by this browser tab. It is not uploaded, saved, or sent to Nova. Notes are ignored. Reset drops the report from the page; close the tab to end the session. You can switch on airplane mode before choosing your file.

One honest limit: JavaScript cannot force memory to be wiped or prove bytes were physically erased, so we don’t claim secure memory erasure — closing the tab ends the session.

  • Zero network requests after the page loads. This site’s security policy literally forbids connections (connect-src 'none'), so it is not a promise you have to take on trust — you can watch it in your browser’s developer tools.
  • No cookies, and no storage of any kind.
  • Notes content is discarded while the file is read. Only a count of rows that had a note is kept.
  • The name of your file is never shown or recorded.
  • Results never appear in any URL.
  • No analytics on this page — we chose not to know whether you ran a report.

What this is not

  • Not medical advice, and not a diagnosis.
  • It cannot measure sleep quality or sleep stages. A file of start and end times records when a timer ran, not how anyone slept.
  • It cannot count true night wakings. A sleep timer often keeps running through a feed, so the report shows only logged interruptions — gaps between recorded intervals — and always says so.
  • It makes no comparisons with other babies and no ranking of any kind.
  • It never infers your baby’s age, because the export carries no birth date. Changes are described by month of the log.
  • It never claims one thing caused another. A feed and a sleep logged near each other are close together in the records, and that is all.

Every definition and threshold is written down on the Methods & caveats page, alongside links to educational guidance from AASM, the CDC, and NICHD.

Questions

Does my file get uploaded?

No. The page makes zero network requests after it loads, and its security policy (connect-src 'none') forbids connections outright. Check it in your browser’s network inspector, or turn on airplane mode before you choose the file.

Do I need an account or an email address?

No. Nothing is gated, blurred, or held back. The full report is free.

Which columns does it need?

The standard Huckleberry export columns. Only Type and Start are strictly required. End, Duration, and the condition columns that record left and right nursing enrich the report when they are present. Column order does not matter and extra columns are ignored. Notes are never read — only counted as present or absent.

What about time zones?

The export stores plain local clock times with no time-zone information. Times are shown exactly as recorded in the export. Your device’s time zone never changes the results. If your family crossed time zones while logging, the original local context cannot be reconstructed — see Methods.

Is this medical advice?

No. It is a descriptive summary of what was logged, using conventions written down on the Methods page, with links to educational guidance from AASM, the CDC, and NICHD.

Is this affiliated with Huckleberry?

No. This is an independent tool made by Nova Baby, not affiliated with or endorsed by Huckleberry. It simply reads the CSV file you export from your own account.
