Strikr privacy policy

Last updated: October 18, 2026

Strikr measures the speed of a soccer kick from video. It is designed so that your videos, your kicks and anything that identifies you stay on your device.

Strikr is made by Kaniku Labs LLC (Ohio, USA), which is the data controller for the little that the website and the app collect. The app sends only anonymous usage data, which you can switch off — see below.

What the app accesses

• Camera — to record a kick in slow motion, only while you are on the recording screen.
• Microphone — to record the sound of the kick with the video, so the strike is there on the clips you share. Only while you are on the recording screen. If you decline, your kicks are filmed silently and everything else works exactly as before: the speed is measured from the picture, never from the sound. The audio is part of the video file on your device and is never sent anywhere.
• Photo library — to let you choose a clip to analyze, to save each kick you film in Strikr to your library, and to save share clips you ask to save. Saving uses add-only access, which lets Strikr add videos but never see the rest of your library; if you decline it, a kick you film stays only in the app. Strikr asks for read access so it can load the original of the clip you pick: Apple hands apps a slowed copy of slow-motion video, and measuring a kick from that copy would report a speed several times too low. Strikr reads only the clip you choose. If you decline, ordinary video still imports through the picker and Strikr tells you when a slow-motion clip cannot be measured.
• Motion sensors — to show a level indicator while you line up the shot.
• Location, while you are using the app — to tag a kick you film with where you filmed it, so your kicks appear on a map and kicks at the same pitch group together. Strikr asks once, on the recording screen, and takes a single reading per recording; it does not track you, and location is never read in the background. The reading is written into your own video file, exactly as your iPhone's Camera app writes it, and stays on your device. Strikr does not look place names up: the map shows only where the kick was, and no coordinate of yours is sent to any geocoding service. If you decline, everything still works — your kicks simply have no place, and clips you import that already carry a location tag are unaffected.

The app asks for no other permissions. Ball detection runs on your device with a bundled model; nothing is downloaded and no video is uploaded.

What the app stores

Videos you record or import (including any location tag they carry), share clips you export, and a JSON diagnostics record for each analysis are stored in the app's own Documents folder on your device. Your kicks themselves, with the measurements Strikr makes from them and the names, feet and categories you give them, are kept in the app's own database, also on your device. If you choose a profile photo, a small copy of it is stored in the app too; it is re-saved from the image alone, so it keeps no location or camera details, and it is never uploaded. If you give your first name, in the introduction or under You → Profile, it is stored in the app so Strikr can greet you; it is never uploaded either. Because the app enables file sharing, the Documents folder is visible in the Files app and in Finder when your phone is connected to a Mac, so you can view, copy or delete those files yourself. You can also delete kicks inside the app, which removes the app's copy of their video and their diagnostics record. Deleting the app removes everything it stores. It does not reach into your photo library: a kick you filmed in Strikr, and any share clip you saved there, stays in Photos until you delete it there.

What the app sends

Strikr has no servers, no accounts and no advertising. It sends two things over the network:

• Anonymous usage data, through TelemetryDeck (https://telemetrydeck.com/privacy/), an analytics service built not to identify people. It records which features are used and whether an analysis worked: for example whether you finished the introduction and, if you answered it there, which option you picked for "How did you hear about Strikr?", whether a kick was recorded in Strikr or imported, that an analysis finished, which measuring method it used and how many seconds it took, that a share clip was made, which screens are opened and for how long, and, for Strikr Pro, where the upgrade screen was opened from, which plan was tapped, whether the purchase was completed or canceled, whether it began the free trial, and whether you are on the free version, the trial or a paid plan. Each record also carries the app's version; the iPhone model, iOS version and screen size; the phone's language, region and time zone; display and accessibility settings such as dark mode and text size; how many days and sessions the app has been used and how long sessions last; and a random identifier for this installation, scrambled before it is sent, that is not linked to your Apple Account, your name or anything else about you. It is not used to track you across apps or websites, and it is not sold.
• App Store traffic: Apple's App Store fetching subscription prices and handling purchases when you open the upgrade screen.

Usage data never includes your videos or any frame of them, your name, your kicks' names, their exact speeds (at most a 20 km/h range), where you filmed, your profile photo, your categories or place names, or anything you type. You can switch it off at any time in Settings → Privacy → Share anonymous usage data; it stops at once.

Files only leave your device when you choose to share them: a share clip through the system share sheet, or the diagnostics records through Settings → Export debug JSON.

Purchases are handled by Apple through the App Store; Strikr only receives whether a subscription is active.

The website and the waitlist

Before Strikr launched on October 15, 2026, this site (strikr.football) had a waitlist form. If you joined it, the only thing collected was the email address you typed. That address is used to tell you Strikr has launched, for occasional updates, and to reply if you write to us. We're emailed each new signup's address, so we can see who has joined. It is never sold, rented or shared with advertisers.

The list is kept, and the emails are sent, by Resend (https://resend.com/legal/privacy-policy), an email service; joining sends you one confirmation email from us. The site is hosted on Vercel (https://vercel.com/legal/privacy-policy), which may log standard request data such as IP addresses to serve and secure it. The site uses Vercel Web Analytics (https://vercel.com/docs/analytics/privacy-policy) to count page views. It sets no cookies and does not identify individual visitors: it keeps a hashed identifier that resets daily, and nothing about you is stored beyond that count.

To leave the list or have your address deleted, email support@kanikulabs.com from the address you signed up with, or reply "unsubscribe" to any email we send.

None of this touches the app. The app has no account, no waitlist and no connection to this site; everything above about the app still holds.
