Privacy
Last updated 22 October 2026. This page covers Nightjar at peakappsstudio.com/oura-export-viewer and its German, French and Japanese pages.
Your export stays on your device
When you open an Oura data export, the page hands the file to a worker script running in the same browser tab. It opens only the files it shows: dailysleep, sleepmodel, dailyreadiness, dailyactivity, dailyspo2, dailystress, dailyresilience, dailycardiovascularage, sleeptime, workout, session, enhancedtag, heartrate, temperature, daytimestress and vo2max. Other files in the ZIP, such as location history, meals, medication, cycle and lab data, are not opened, and “What was read” on the page lists them by name.
Nothing from the export is sent to a server, ours or anyone else’s, and nothing from it is stored in your browser. Closing or reloading the tab discards it. The cards, the PDF report and the CSV are made in the tab and saved straight to your device.
What the page does send
- The Pro license check. When you paste a license key, the page sends that key and the product’s number to Gumroad’s license check (api.gumroad.com) and keeps the answer in your browser’s local storage, so Pro stays on. It checks again in the background once a week. No export data goes with it.
- Visit counts. We count page visits with Cloudflare Web Analytics, which uses no cookies and no personal data. It never sees your files.
- Buying Pro. The buy button opens Gumroad, which handles payment under its own privacy policy. We get your email address and the purchase from Gumroad, to answer questions and refunds.
Oura
Nightjar never connects to your Oura account and never asks for your Oura login. It is an independent tool by Peak Apps Studio and is not affiliated with, endorsed by or sponsored by Oura Health Oy.
Not medical advice
Nightjar shows the numbers in your own export with plain explanations. It is not a medical device and does not diagnose, treat or advise.
