Hadar is published by Geist Labs LLC ("Team Hadar", "we", "us"). This policy explains what Hadar does with your information. It is written to be read, not to be survived.
The short version: Hadar has no account system, collects no analytics, and stores none of your Delta documents. Most of what Hadar knows about you never leaves your phone at all.
1. We do not have an account for you
Hadar has no sign-up, no login, no password, and no email address on file. We do not know your name, your employee number, your base, or your seniority. There is no user record anywhere on our systems to look you up in, because we never made one.
The one time we could learn your email address is if you type it into the Contact us form yourself, because you want an answer. That message becomes an ordinary email to us and is not stored on our server or added to any record. See section 7.
This is deliberate. If we do not store it, we cannot lose it, sell it, or be compelled to hand it over.
2. What never leaves your phone
The following is created and kept only in Hadar's storage on your device. It is not uploaded, backed up to us, or visible to us in any form:
- Your pilot profile — name, employee number, base, fleet, seat, pay status
- Your logbook, including every entry, block time and night time
- Any seniority list you add, and every seniority result calculated from it
- Your schedule, trips, and bid scenarios
- FAR 117 and reserve calculations
- Your theme, settings, and backup files
If you uninstall Hadar, this data is deleted with it. Android's own automatic backup may include some of it in your personal Google account backup — that is a transfer between you and Google, and we are not part of it.
3. Delta documents are read and thrown away
When you paste or upload a timecard, Pay Activity Statement, rotation, or bid package, Hadar sends that text to our server to be interpreted, because the pay rules that read it are too large and change too often to live inside the app.
That text is:
- held in memory only, for the seconds it takes to parse
- never written to a disk, a database, or a log file
- discarded the moment the answer is sent back to your phone
We keep the answer for no one. The next time you open Hadar, the results you see are the ones stored on your own phone, not fetched back from us.
4. Location — only if you turn it on, and never to us
Hadar can show you the current driving time from where you are to the airport. It shows that time as a plain fact and nothing more — it does not tell you when to leave, and it does not know your sign-in time. Turning a drive time into a departure decision is yours.
- It is off until you enable it in Settings.
- The routing service is one you choose and connect with your own key (currently TomTom, HERE, or Google Routes). Your location goes from your phone straight to that provider.
- Your location is never sent to Hadar's server and is never stored by us. We do not receive it, and we could not produce a history of where you have been if asked.
- If you enable background refresh, the same is true — the phone updates the number quietly so it is current when you open the app, still talking only to your chosen provider.
- Your use of that provider is governed by that provider's own privacy policy.
You can revoke location access at any time in Android's settings, or turn the feature off inside Hadar, and the card simply stops offering a drive time.
5. Calendar — only if you turn it on, and never to us
If you switch on schedule sync, Hadar writes your trips into a calendar on your device. That happens entirely between Hadar and your phone's calendar. Our server is never involved and never sees your schedule. Sharing a trip as a calendar file sends it wherever you choose to send it, using your own apps.
6. When Hadar cannot read something
Delta changes its documents without telling anyone. When Hadar meets something it does not recognise, it can tell us so the parser can be fixed for everyone. What gets sent depends on the case:
- Ordinary parse failures: we receive only the shape of what failed — how many lines, which section, which pattern did not match. The content itself is not sent. No names, no employee numbers, no pay figures, no dates, no flight numbers.
- An unrecognised flight marker: a single line of your rotation is sent verbatim, because that marker cannot be decoded without the text around it. Hadar shows you that exact line and asks your permission before sending it, every time, unless you choose to be remembered. If you say no, nothing is sent, and "no" is remembered just as durably as "yes". Nothing else from the rotation travels with it — no other legs, no employee number, no pay, no rotation number, no dates.
Every report also includes your app version, your phone's model, and its Android version, so we can tell whether a problem is specific to one build or one device. Reports reach our own server and a push-alert service that notifies us; they are used only to fix parsing, never to build a profile of you.
7. When you write to us
Settings has a Contact us form. It sends only what you type into it. Nothing is attached from your timecards, your schedule, your logbook or anything else on your phone, and the form does not accept screenshots or files of any kind — deliberately, because a screenshot of a timecard is the document itself.
- The message is not stored. It reaches our server, is turned into an email, and is sent. It is not written to a file, a log, or a database on the way through. The email in our mailbox is the only copy that exists.
- The email address is optional and only used to answer you. Leave it blank and your message is still read; you simply cannot be replied to. If you give one, it travels with the message, it is not stored on our server, and it is never added to a mailing list, sold, or used to contact you about anything other than your own message.
- We keep your message in our mailbox for as long as it takes to deal with it, the same way any email you send to anyone sits in their inbox. Ask us to delete it and we will.
- Your app version, phone model and Android version travel with it, so we can tell whether a problem belongs to one build or one phone.
- We are notified that a message arrived, not what it says. The alert that reaches our phone contains only the category you picked, if you picked one. Your words and your address are not in it.
Please do not put anything in the message you would not want to send by ordinary email — it is ordinary email once it leaves us.
8. No analytics, no advertising, no tracking
Hadar contains no analytics library, no crash-reporting service, no advertising network, and no third-party tracking of any kind. There is no advertising ID, no device fingerprint, and no usage telemetry. Nobody is measuring which screens you open or how long you stay.
9. Other services Hadar talks to
To draw weather and maps, Hadar (or our server on its behalf) requests public imagery and data from public sources including the U.S. National Oceanic and Atmospheric Administration, NASA, the U.S. National Weather Service, Iowa State University's Mesonet, EUMETSAT, the Japan Meteorological Agency, and OpenFreeMap/OpenStreetMap for map tiles. These are requests for public pictures and public weather data. Nothing about you is attached to them.
Hadar also checks our server for app updates and downloads them when you accept.
10. Where our server is, and what it logs
Our server is hosted in Germany. We do not log IP addresses and we do not keep request logs that would tie activity back to a device or a person. Traffic is encrypted in transit.
11. Payment
Subscriptions are handled by Google Play. We never see your card, your billing address, or your Google account. Google tells us only whether a subscription is valid. Google's handling of your payment information is governed by Google's own privacy policy.
12. Your rights, and how little there is to exercise them on
Because we hold no account and store no documents, there is generally nothing of yours for us to show you, correct, or delete on request.
- To delete everything Hadar knows about you: uninstall the app, or use Settings to clear its data. That is genuinely all of it, with one exception: a message you sent us through Contact us is sitting in our mailbox like any other email you have ever sent anyone. Ask and we will delete it.
- To stop the optional flows: turn off location, calendar sync, or parse-failure reports in Settings at any time.
- If you are in a jurisdiction granting rights of access, correction, deletion, or portability (for example the GDPR in the EU/UK, or state privacy laws in the U.S.), you may still contact us at the address below and we will respond. In most cases the honest answer will be that we hold nothing about you.
13. Children
Hadar is a professional tool for airline pilots and is not directed at children. We do not knowingly collect information from anyone under 16.
14. Changes to this policy
If this policy changes in a way that affects what leaves your phone, we will say so in the app before the change takes effect, not quietly edit this page. The effective date at the top always reflects the current version.
