Terms of Service

These terms govern your use of uls-tracker (the "Service"), an independent web service for tracking U.S. amateur radio callsign licensing data published by the FCC.

Last updated: 6 September 2026

1. Who we are

The Service is independently operated in Texas under the name Ice Code Studio ("we", "us"). Contact: [email protected].

2. Accounts

Accounts are created and accessed by emailed magic link — we do not issue or store passwords. You are responsible for the security of the email inbox you sign up with: anyone able to read that inbox can sign in as you. Sign-in links expire 15 minutes after they are issued and can be used once.

You must be at least 13 years old to create an account. One person or organization per account; do not share credentials or session cookies.

3. Subscriptions and billing

• The Service has a free tier and a paid tier: $4/month or $36/year. Current prices are on the pricing page and are stated in U.S. dollars.
• Payments are processed by Stripe. We never see or store your full card number — see the privacy policy.
• Paid plans renew automatically at the end of each billing period (monthly or annual) until cancelled. You can cancel any time from the Stripe customer portal, linked from your billing settings. Cancelling stops future renewals; the portal shows the date your access ends, which we set to the end of the period you have already paid for.
• We do not prorate or refund partial periods. If you believe you were charged in error, email us within 30 days of the charge and we will review it. Refunds, when given, are at our discretion and issued through Stripe. This does not limit any rights you have under applicable law or through your card issuer.
• If we change prices, existing subscribers will be notified by email before the change takes effect on their plan.
• If a payment fails, paid features may be suspended until billing is restored. Your watchlist and account data are retained during this time.

4. Acceptable use

You agree not to:

• Scrape, crawl, or bulk-download the Service outside the documented API and its rate limits, or share an API key with third parties.
• Circumvent tier limits — for example by creating multiple accounts to exceed watchlist caps or free-tier quotas.
• Use callsign, licensee, or address data from the Service to harass, stalk, dox, or send unsolicited bulk mail to any person.
• Resell or redistribute the Service's derived data (availability dates, confidence labels, genealogy chains) as a competing product.
• Interfere with the Service's operation, or attempt to access accounts, data, or systems that are not yours.

Note that the underlying FCC ULS records are U.S. government public data and are not ours to restrict. These terms cover the Service and the work we do on top of that data, not the public records themselves.

5. Data accuracy — no warranty

The Service is provided "as is". Availability dates are a model of FCC §97.19, computed from imported ULS records, not a statement of fact from the FCC. Records can be late, incomplete, corrected retroactively, or superseded by FCC action we have no visibility into.

Do not treat anything on this site as legal advice or as a guarantee that a callsign will be available on a given date. Verify against the FCC's own systems before filing a vanity application or making any decision that costs you money or a filing window. We are not liable for a missed slot, a rejected application, a filing fee, or any other loss arising from reliance on our data.

6. Availability of the Service

We aim to keep the Service running continuously and to re-import FCC data each morning, but we do not offer an uptime guarantee or SLA. Maintenance, upstream FCC outages, and file-format changes can interrupt or delay updates.

7. Limitation of liability

To the maximum extent permitted by law, our total liability to you for any claim relating to the Service is limited to the amount you paid us in the twelve months before the claim arose. We are not liable for indirect, incidental, or consequential damages, including lost profits or lost opportunities.

8. Termination

There is no self-service way to delete your account yet. Email [email protected] and we will delete it — email address, watchlist, preferences, API keys, and sessions — within 30 days, keeping only the billing records we are required to retain. We may suspend or terminate an account that breaches these terms, and will give notice by email where we reasonably can. On termination we delete or anonymize your account data as described in the privacy policy.

9. Changes to these terms

We may update these terms. Material changes will be announced by email to registered users and reflected in the "last updated" date above. Continued use after a change takes effect means you accept the revised terms.

10. Governing law

These terms are governed by the laws of the State of Texas, USA, without regard to its conflict-of-law rules. Any dispute arising from these terms or the Service will be brought in the state or federal courts located in Texas.

11. Independence

uls-tracker is not affiliated with, endorsed by, or sponsored by the FCC, the ARRL, AE7Q, or any vanity-application filing service. See about for how the data is sourced.
