Privacy Policy
Last updated 4 November 2026
Pilot Night Calc is built to need as little of your data as possible. You don't create an account, and your logbook is never stored. This policy explains what we do handle, why, and for how long.
Who we are
8200 RAN INTELLIGENCE S.R.L., Calea Dorobanților nr. 7, ap. 15, 400117 Cluj-Napoca, Romania; CUI 44564621; Nr. Reg. Com. J12/3259/2021 (the controller). Contact: office@ranintelligence.com.
What we handle and why
| Data | Purpose | Legal basis | Kept for |
|---|---|---|---|
| Your uploaded logbook file | To calculate night time and send the result back to you | Contract (GDPR art. 6(1)(b)) | Not stored. Processed in memory and discarded when the response is sent. Never logged. |
A random visitor ID in a cookie (pnc_id) and a keyed hash of your IP address (for IPv6, of your network prefix), with the time of your last free calculation | To apply the free limit of one file per week and prevent abuse | Legitimate interest in fair use and in protecting the service (art. 6(1)(f)) | 8 days after your last free calculation |
| For paid files: the Stripe payment reference and a SHA-256 fingerprint of the file (not the file itself) | To tie your payment to your file so you can recalculate it | Contract (art. 6(1)(b)) | 90 days |
| Server logs: IP address, time, page requested, browser type | Security and troubleshooting | Legitimate interest (art. 6(1)(f)) | 14 days |
| Coupon codes you enter, and for a coupon that unlocks a file, a SHA-256 fingerprint of that file (not the file itself) | To check the coupon, apply its limit (normally one file) and let you recalculate the same file | Contract (art. 6(1)(b)) | The file fingerprint: 90 days. For the coupon itself we keep only when it was used and how many flights the file had, nothing that identifies you |
| Usage statistics: daily totals (files processed, flights, night definition chosen, checkouts) and a keyed hash of your visitor ID to count unique visitors | To understand how the service is used, spot problems and plan improvements | Legitimate interest (art. 6(1)(f)) | Daily totals don't relate to any person and are kept as long as the service runs. The hashed visitor IDs are deleted after 35 days |
The sun reference table we keep (sunrise, sunset and twilight times per airport and date) is public astronomical data and contains nothing about you.
Cookies
We set one cookie, pnc_id. It is strictly necessary to provide the free tier fairly (one file per week), so it doesn't need consent. It holds a random ID, is sent only to this site, can't be read by scripts, and expires after 400 days. We use no analytics, advertising or tracking cookies, and no third-party analytics: the usage statistics above are counted on our own server. The human check runs in your browser (a small proof-of-work calculation) and sends nothing to third parties.
Payments
Payments are handled by Stripe Payments Europe, Ltd. (Ireland) on a page hosted by Stripe. Your card details and billing information go directly to Stripe and never reach our server. Stripe processes them under its own privacy policy. We receive the payment status, amount and the email address you give at checkout, and we keep payment records for as long as Romanian accounting law requires (currently 10 years).
Who processes data for us
Our hosting provider, Akamai Connected Cloud / Linode (servers in Frankfurt, Germany), acts on our instructions under data processing terms. Stripe acts as described above. We don't sell or share your data with anyone else. Where a provider handles data outside the EU, the transfer is protected by the European Commission's Standard Contractual Clauses or the EU-US Data Privacy Framework.
Your rights
You can ask for access to, correction or deletion of your data, restrict or object to its use, or receive a copy. Write to office@ranintelligence.com. Because we store so little, we may only be able to find your data if you tell us your Stripe receipt number. You can also complain to the Romanian data protection authority, ANSPDCP (dataprotection.ro), or to the authority where you live.
Changes
If we change how we handle data, we'll update this page and the date at the top.
