FingerPick1. Scope
This policy applies to the current FingerPick release and explains how information is handled when you use its selection, grouping, turn-order, and support features.
2. Core touch processing
Finger positions used for group selection, team splitting, and turn order are processed temporarily on the device. FingerPick does not need participant names, accounts, contacts, photos, or precise location for these core functions.
3. Device permissions
The core experience uses screen touch and may use haptic feedback. It does not require access to contacts, camera, microphone, photos, or precise location. Any change in the release build will be disclosed before launch.
4. Storage and sharing
Core selection results and temporary touch positions are not uploaded for the selection to work. FingerPick does not sell participant information or use touch data for targeted advertising.
5. Usage analytics
FingerPick records how the app is used: which game modes are opened, whether a draw is completed or abandoned, how many participants a round actually had, which interface language and theme are in use, and which screen an action happened on. On Android these records go to Google Firebase Analytics. On both Android and iPhone or iPad they also go to our own reporting service, operated by Yayin Guanjia, together with a random installation identifier, the app version, and the operating-system version. Our reporting service also receives when the app is opened or brought back to the foreground, how long it stays in use, whether the app could confirm your subscription status at launch, and whether these reports are being delivered (for example how many are waiting or had to be retried). These records are not linked to a name, an account, or a contact, because the app has none, and they never include names you type or the result of any individual draw for a named person. Firebase additionally collects standard technical information such as app version, operating-system version, device model, and country. You can turn all of this off at any time in Settings → Legal → Usage statistics; the switch covers both destinations, and the app keeps working normally with it off.
6. Purchases and subscriptions
FingerPick is used with a weekly subscription. When a limited free tier is offered, each game can be played a set number of times without subscribing; the number of free plays used is kept only on your device. Purchases are processed by the app store on your device, not by us. We never receive or store your payment-card details. We do receive, from the store, whether your account currently holds a valid subscription, the product identifier, the transaction and order references, and whether a free trial applied. When you subscribe, the installation identifier described in section 8 is attached to the purchase as the store’s account token (Apple’s app account token, Google Play’s obfuscated account ID), so the store’s record of that purchase can be matched to this installation; it carries nothing else. When the app confirms your subscription status, the report includes a one-way hash (SHA-256) of the app identifier and the store’s original transaction reference, used to group the confirmations of one subscription together, and a yes/no flag recording whether the purchase carries this installation’s identifier. This is used only to unlock the app, to confirm your subscription status, and to report revenue to our attribution provider. Your subscription status is also cached on your device so the app works while offline.
7. Install attribution and advertising
FingerPick does not display advertising inside the app. We do measure which advertising campaign led to an installation and whether that installation resulted in a subscription. On Android this uses Adjust, which receives your Google Advertising ID, device and network information, and subscription transaction references for verification against Google Play. On iPhone and iPad it uses Apple’s own AdServices attribution, which provides a short-lived attribution token rather than an advertising identifier, and no tracking permission prompt is involved. On both platforms an installation identifier generated by the app, the store transaction reference, the subscription product and price, and basic device, locale, and time-zone information are also sent to our attribution provider, Yayin Guanjia, so that a subscription can be connected to the campaign that produced the installation. Yayin Guanjia also uses the IP address of that connection to determine your approximate country; this country-level location is stored with the attribution record, while precise location is never collected. Touch positions and selection results are never used for advertising and are never sent to an advertising network. On Android you can limit this in your device settings under “Delete advertising ID” or “Opt out of Ads Personalisation”.
8. Sharing, retention, and security
We share information with the service providers named in this policy — Google Firebase for analytics, Adjust and Apple AdServices for install attribution, Yayin Guanjia for attribution and usage reporting, and the app store that processes your purchase — and only for the purposes described here. We do not sell participant information, finger positions, or local selection results, and those are never uploaded. The installation identifier we generate is a random value created on your device; it is not your name, your account, or a device serial number, and clearing the app’s data or uninstalling the app discards it. Analytics and attribution records are retained by those providers according to their own retention periods. Information you choose to send by email is handled only to answer your request and meet applicable legal obligations.
9. International processing
Finger positions and selection results stay on your device. Analytics, attribution, usage and purchase-verification information is processed by Google, Adjust, Apple, and Yayin Guanjia, which operate internationally, so that information may be transferred to and processed in countries other than yours — including the United States and, for Yayin Guanjia, mainland China — under the safeguards those providers apply. If you contact us by email, your message may be processed by the email services you choose to use and by our business email service.
10. Your choices and rights
You can turn usage analytics off at any time in Settings → Legal → Usage statistics; the switch covers both reporting destinations. On Android you can reset or delete your advertising identifier in your device settings, which stops attribution from identifying your device; on iPhone and iPad no advertising identifier is used, and Apple’s attribution token expires on its own shortly after installation. You can manage or cancel your subscription in your app store account; the paywall also links there directly. Clearing the app’s data or uninstalling FingerPick removes the locally stored preferences, the cached subscription status, and the installation identifier described in section 8 — a later reinstall is counted as a new installation and cannot be linked to the previous one. Step-by-step deletion instructions, including what is deleted and what is kept, are at https://fingerpick.yayinintl.com/products/fingerpick/data-deletion. To ask about information you sent to support, or to request deletion of analytics or attribution records associated with your device, email contact@yayinintl.com with “FingerPick Privacy Request” in the subject. We usually reply within a few business days.
11. Children
FingerPick is a general group utility. Children should use it with a parent, guardian, teacher, or other responsible adult where appropriate. The core chooser is not designed to collect a child’s name or contact details.
12. Changes and operator
We may update this policy when the release build, service providers, legal requirements, or product features change. FingerPick is operated by YAYIN INTERNATIONAL TRADING LIMITED, Room 1401, 14/F., Wing On Centre, 111 Connaught Road Central, Hong Kong. Email: contact@yayinintl.com.
