Privacy at Onsider
The short version: Onsider's own code collects nothing about you — no account, no sign-up, no first-party analytics. The free tier shows ads through Google AdMob, which is the one part of the app that collects data; iOS asks for your tracking permission first, you can decline, and the one-time £1.99 ad-free purchase stops the ad system from running at all. Here's the long version, in plain English.
What Onsider itself collects
Nothing. There are no accounts and no sign-up. Your mission setup (the occasion, the crowd, your goal) is stored only on your device. We run no analytics of our own, we add no tracking of our own, and our own code never sends anything about you anywhere. Deleting the app deletes everything it stored. The app is offline-first and works with zero signal — most of the time nothing leaves your phone at all.
Ads (Google AdMob) — the one thing that does collect data
The free version shows a small number of clearly-labelled native ads, served by Google AdMob. Like any ad network, AdMob collects data when it serves ads. Per Google's own disclosure for the AdMob SDK, that can include:
| Data | What it is |
|---|---|
| Device ID (advertising identifier / IDFA) | Used for advertising — including, with your permission, tracking across other companies' apps |
| Advertising data | Which ads were shown and how they performed |
| Product interaction | Ad-related interactions, e.g. taps on an ad |
| Coarse location | An approximate location derived from your IP address |
| Performance & crash data | Diagnostics about how the ad components ran |
How Google uses this data is described in “How Google uses information from sites or apps that use our services.”
Tracking, and how to say no
On first launch (in the UK/EU after a consent form) the app shows Apple's standard App Tracking Transparency prompt. Your choice does exactly what it says:
- Allow — AdMob may use your device's advertising identifier to show more relevant (personalised) ads. This is the only “tracking” in Onsider.
- Ask App Not to Track — the identifier is withheld and ads are non-personalised. The app works identically either way; nothing is locked behind your answer.
You can change your mind any time:
- iOS Settings → Privacy & Security → Tracking → Onsider;
- in the UK/EU, Field Kit (Settings) → “Manage ad consent” re-opens the consent form;
- or go ad-free (below) and the question disappears entirely.
The £1.99 ad-free purchase removes the data collection too
The one-time ad-free purchase doesn't just hide ads. Once your ad-free entitlement is active, the app does not start the ad system at all from your next launch — no consent form, no tracking prompt, no AdMob SDK running, no ad-related data collection. Combined with Onsider collecting nothing first-party, an ad-free copy of Onsider collects no data about you whatsoever.
The purchase itself is handled entirely by Apple. We never see your payment details, and we keep no record of you as a purchaser — the entitlement lives in your Apple account and restores automatically on any new device.
Match data (fixtures and the scores relay)
To show fixtures and delayed final scores, the app makes two kinds of anonymous fetches. The fixture schedule comes straight from the OpenFootball public-domain project (CC0), served from its public CDN. Delayed final scores come through a small relay we run on Cloudflare — the relay exists to keep the upstream API's token server-side, and the app sends it only a non-personal app key that is identical in every copy of the app. Neither request carries an account, an identifier, or anything about you, and relay responses are cached server-side for everyone. Like any web request, each server necessarily sees the connecting IP address at the transport level; we don't store or profile per-user requests. Results data comes from the football-data.org API.
AI
Nothing you do in Onsider is sent to any AI service — ours or anyone else's. The lines you see are hand-curated and ship as written; the app is built so that any phrasing variation it ever performs runs entirely on your iPhone using Apple's on-device models, with the underlying facts locked. Off-device AI is not part of the app, full stop.
This website
onsider.app sets no cookies, runs no analytics or third-party trackers, has no forms, and self-hosts its fonts — visiting it doesn't quietly call out to anyone else. It's served by Cloudflare Pages, whose infrastructure keeps standard, transient server logs (as with any host); we don't use them to identify visitors.
Your rights (UK/EU)
Onsider is made in the UK, so UK GDPR (and the EU GDPR where it applies) governs the little that happens here. The lawful basis for personalised ads is your consent (the consent form + the tracking prompt — withdrawable as above); non-personalised ads and the anonymous scores fetch rest on legitimate interests. Because we hold no account or profile about you, rights like access, correction and portability usually have nothing to operate on — the data that exists lives on your device and is erased when you delete the app. Ad-side data is processed by Google under its own terms (linked above). You can always complain to the ICO (ico.org.uk), though we'd rather you emailed us first.
California: “Do Not Sell or Share My Personal Information”
We don't sell personal information, and our own code shares none — we have none to share. Serving personalised ads via a third-party ad network can count as “sharing” for cross-context behavioural advertising under the CCPA/CPRA. To opt out of that sharing: choose Ask App Not to Track on the tracking prompt (or switch it off later in iOS Settings → Privacy & Security → Tracking), withdraw consent via “Manage ad consent”, or buy the ad-free upgrade — any of these stops personalised ads. We don't knowingly sell or share the personal information of anyone under 16.
Children
Onsider is not directed at children and we don't knowingly collect information from anyone under 13. There are no accounts or profiles, and ad content is capped at a general-audience rating.
Changes
If any of this changes, we'll update this page and the date below. Given how little there is, we don't expect drama.
