For the CONVERT UNITS iOS app · Last updated 25 July 2026
The short version. CONVERT UNITS has no accounts and no sign-in. Your favourites, saved conversions and settings are stored on your device and are not sent anywhere. The app makes one kind of network request — fetching exchange rates — and that request contains nothing about you. The app shows ads from Google AdMob, which is the only third party that receives any data.
strikespark does not collect, store or receive any personal information from this app. There is no account to create, nothing to log in to, and no server operated by us that your device talks to.
The app saves the following locally, so it can remember what you were doing. This data stays on your device, is not transmitted to us, and is removed when you delete the app:
If you use iCloud device backups, this data may be included in your own backup, under your Apple account. We have no access to it.
To convert currencies, cryptocurrencies and precious metals, the app downloads a public table of exchange rates from a free public rates API, served via Cloudflare Pages and the jsDelivr CDN.
This is a plain request for a public file. It does not include your identity, your location, or anything you typed into the app — the same file is served to every user. As with any request to any website, the servers involved receive your device's IP address and can log it; that is handled under those providers' own policies, not ours.
The app displays advertising supplied by Google AdMob. To serve and measure ads, Google may collect and process device and advertising data. Google's handling of that data is described in How Google uses information from sites or apps that use our services.
This app does not ask for App Tracking Transparency permission and does not access your device's advertising identifier (IDFA) for tracking across other companies' apps and websites. You can further limit ad personalisation in Settings → Privacy & Security → Tracking and Settings → Privacy & Security → Apple Advertising on your device.
The app includes no analytics or crash-reporting service. Apple provides developers with anonymous, aggregated App Store statistics — such as download counts and crash totals — which cannot identify individual users, and only if you have opted in to sharing analytics with developers in your device settings.
CONVERT UNITS contains no in-app purchases and no subscriptions. It never asks for payment details.
This app is not directed at children under 13, and we do not knowingly collect any information from children. Since the app collects no personal information from anyone, there is nothing for us to delete — but if you have a concern, please write to us at the address below.
If the app's data practices change, this page will be updated and the date at the top will change with it. Material changes will also be noted in the app's release notes.
Questions about this policy, or about privacy in the app, can be sent to strikespark.feedback@gmail.com.
