What we
store.

One ID. Your volume. That's it.

When you open the site we save a few things in your browser's localStorage:

• numa.sid— a random UUID. One per browser, never per tab. Used to count concurrent listeners and remember which tracks you've voted on. Has no link to you as a person.
• numa.volume, numa.muted — your player settings.
• numa.shoutout.last, numa.song.pending — short-lived (5–10 min) recovery tokens for in-flight booth submissions. Auto-expire.

We do notset tracking cookies. We don't read your canvas, fonts, audio context, or anything else fingerprintable.

Clear site data for numaradio.com in your browser settings and all of the above is gone instantly.

Hashed IPs. No raw addresses.

When you submit something — a shoutout, a song request, a music upload — we record a one-way hash of your IP address (SHA-256 with a server-side salt, truncated to 32 hex chars). This can't be reversed back to your IP, but it lets us rate-limit abuse from a single source.

We never store the raw IP. Standard server access logs at our hosting providers (Vercel for the site, Cloudflare for the CDN edge) keep IPs for short rolling windows under their own retention policies — those aren't under our direct control.

The hashed IP lives on the table that holds the thing you sent (your shoutout, your song request, your upload). Retention windows are listed in section 03 below.

Your votes, requests, shoutouts, and uploads.

Votes. When you thumbs-up or thumbs-down a track, we record (track, your numa.sid, up or down). No IP, no name. Used to remember your vote on the next page load and to influence rotation. Kept while the track is in the catalog.

Listener counts. Every 30 seconds while the tab is visible, your browser pings the server with your numa.sid. Rows older than two minutes are deleted automatically.

Shoutouts.The text you write, the optional name you give, and your hashed IP. Aired shoutouts stay on the catalog (so listeners can scroll the wall). Shoutouts that didn't make it to air — blocked, held, or failed to deliver — are deleted after 90 days.

By sending a shoutout you also agree that your typed message and the name (or handle) you supplied may appear in promotional clips on the station's social media accounts (TikTok, Instagram Reels, YouTube Shorts, and X / Twitter) — the same words that aired on the live broadcast. If you'd rather your shoutout stayed on-air-only, leave the name field blank or email hello@numaradio.com and we'll exclude it (and pull any clip already posted within 24 hours).

Song requests.Your prompt, your handle, and your hashed IP. If we generated a track from your prompt and aired it, the request stays linked to that track. Requests that didn't result in an aired track are deleted after 90 days.

Music submissions (artists). Your name, email, the audio file, optional cover art, and your hashed IP. Lifecycle:

• While pending: audio + metadata sit in our submission storage waiting for review.
• If we approve: audio moves into the broadcast catalog under a new asset row, the submission's storage copy is deleted. Your name and email stay on the submission record so we can reach you.
• If we reject: audio + cover are deleted from B2 immediately. The row stays with the rejection reason for 30 days, then is permanently deleted.
• If you withdraw: see section 06.
• Newsletter opt-in: if you tick the optional “keep me posted” box, we'll use your email for occasional Numa Radio updates. Every newsletter includes a one-click unsubscribe; you can also email us to be removed.

A short list of processors.

We don't sell, share, or export your data for advertising or analytics. We do route some of it through services that help us run the station — listed here in full, with what each one sees:

• MiniMax(China, US edge). Receives the text of your shoutouts and song requests for moderation and rewriting, and the text prompt for AI music generation. Receives the optional sender name. Doesn't see your IP, your hashed IP, or anything else.
• Deepgram (US). Receives the final on-air script (rewritten by us) and returns the synthesised voice. No personal info.
• Brave Search (US). Receives generic topic queries the host uses for context (e.g. “weather Tokyo today”). Never receives your content.
• GetSongBPM (US). Used by our internal music-curation tool to look up the tempo and musical key of currently-charting songs (title + artist only, both already public chart data). Never receives listener data, IPs, or anything you submit.
• OpenRouter (US). Receives album-art prompts for AI image generation when a song request is made. Never receives your name, email, or IP.
• Backblaze B2 (Frankfurt, EU). Stores the audio files and album artwork — yours and ours.
• Vercel(London edge). Hosts the site you're on. Sees standard server access logs. We also use Vercel's built-in Web Analytics to count anonymous page views — it sets no cookies, doesn't fingerprint, and uses a daily-rotating hash so you can't be followed across sites or across days.
• Cloudflare (US, global edge). CDN + access control. Sees standard server access logs.
• Neon (EU, Postgres). The database that holds the rows described in sections 02 and 03.

Some of these are outside the EEA. By submitting content through the site you're aware it may transit non-EEA infrastructure. We don't use any of them for advertising, profiling, or building a profile on you.

Access. Erasure. Done within 7 days.

You can ask us to:

• Tell you what we have— send an email; we'll write back with everything tied to your IP-hash, your numa.sid (paste it from devtools → Application → Local Storage), or your email address.
• Delete what we have— same email, we'll wipe it. For uploaded music, we distinguish withdrawal from full deletion — see section 06.
• Correct what we have— mistyped your name on a submission? Email us, we'll fix it.

Email hello@numaradio.com for any of the above. We aim to respond within 7 days.

If you're in the EU/UK and unhappy with how we've handled a request, you can lodge a complaint with your national supervisory authority — but please give us a chance to fix it first.

What you're
agreeing to.

When you upload a track to Numa Radio you confirm:

• The recording and the composition are your work, or you have all rights to broadcast them.
• You authorise Numa Radio to air the track on its 24/7 audio stream and on its public YouTube simulcast (the same broadcast, mirrored to YouTube Live so listeners can watch on the YouTube channel as well as listen via the audio stream). If your rights deal with a label or distributor restricts YouTube distribution, please don't submit.
• You authorise Numa Radio to use promotional clips of the track on the station's social media accounts — TikTok, Instagram Reels, YouTube Shorts, and X (Twitter) — to promote the broadcast. Your artist name, track title, and (where the post is built around your track specifically) cover artwork may appear on screen. We don't use any other personal information of yours in those clips.
• You're solely responsible for the rights status of what you submit. Numa Radio is not liable for disputes arising from material you upload that turns out not to be yours to share — including any YouTube Content ID claims.
• The artist-name and track-title fields are for credit only. Any URL pasted into those fields (Suno, Bandcamp, Spotify, etc.) is automatically stripped before the track goes to air or shows up in our library. The station doesn't link out from on-air credits.

Default lane. The submission form defaults to Permanent rotation — you can switch to One-off airingbefore sending if you'd rather we air the track once and not add it to the library.

Withdrawing your track. Email hello@numaradio.com and we'll pull it from rotation within 48 hours. What happens to your contact info depends on the lane you chose at submit time:

• Permanent rotation. We pull the track and delete the audio. Your name + email stay on the (now-withdrawn) record so we can reach back out — for example, if we lose the file and want to ask whether you'd like to re-submit.
• One-off airing. We pull the track and delete the audio AND scrub your name + email from the record. Only an anonymised audit row remains.
• Total erasure. Either lane — say so explicitly in your email and we'll wipe the row, the track, and every associated asset. Nothing of yours stays on our side.

Copyright complaints. If you believe a track on the station infringes your rights, email hello@numaradio.com with the URL of the track, your contact details, and a statement that you own (or represent the owner of) the copyrighted work. We act on these within 24 hours.
