Privacy
Straight to the point: here is everything HamProp keeps about you, what each piece is for, and how to ask us to delete it. If anything is unclear, write to [email protected].

Who runs this
HamProp is a personal project by Jony, LU7DV, an Argentine radio amateur. It is not a company and nobody else has access to the data. Contact: [email protected].
What we keep
Your callsign. It is the key to the whole system and it is public information by definition: it is in your country's registry and on QRZ.
Your email, if you gave one. It is optional. It is used to recover your account, verify it and send you the getting-started guide. We never sell, rent or share it, and we never use it for advertising.
Your Telegram chat ID, if you linked the bot. It is a number that identifies the conversation. We never see your phone number — Telegram does not give it to bots.
Your alerts: the filters you created and how often they fired.
Your log, if you uploaded it. This is the most sensitive piece, so we treat it differently:
- From the ADIF file we extract only slots: DXCC entity, band, mode and whether it is confirmed.
- We do not keep dates, times, reports, names, grids or comments from your QSOs.
- The uploaded file is deleted after processing.
The reason is concrete: a full log tells where you were, when, and who you talked to. None of that is needed to tell you what you still need, so we do not keep it.
Preferences: language, time zone, quiet hours.
What we use it for
To run the service and nothing else: match cluster spots against your filters, send you the alert, and let you manage everything from the web. We also look at aggregate numbers — how many users, which filters are most used — to decide what to improve. That identifies nobody.
No advertising, no profiling, no data selling. There is nothing to sell: the project runs on donations.
Who we share it with
Only the services needed to make this work:
- Telegram — your alerts travel through it. Their privacy terms apply.
- Brevo — sends the emails. Sees your address and the message.
- Cloudflare — sits in front of the site and sees connections.
- Ko-fi — only if you donate. We never see your card or payment details; on our side only your callsign is listed as a supporter, without the amount.
Spots come from the worldwide DX cluster network — public information that radio amateurs publish themselves.
Cookies
We use a single cookie, the session one, to keep you logged in. It is technical and necessary: without it you could not sign in. There are no advertising or third-party tracking cookies.
Where the data lives
On a private server in Argentina and on the site's hosting. Daily backups are kept for 14 days and then deleted automatically.
How long
As long as you have an account. If you ask us to delete it, everything goes: alerts, log slots, Telegram link and email. Cluster spots are not yours and do not identify you, so they stay.
Your rights
At any time you can ask for a copy of your data, ask us to correct it, or ask us to delete the account entirely. Write to [email protected] from your account email, or message us on Telegram if you linked it. We answer within a few days and you do not have to explain why.
If you are in the European Union, these are your rights under GDPR: access, rectification, erasure, portability and objection.
Minors
HamProp is meant for licensed radio amateurs. If you are under age, use it with your parents' knowledge.
Changes
If this changes in any meaningful way, we will tell you on Telegram or by email. The date above says when it last changed.
