Chicken Masterclass developed by VMNS Techno Labs ("we," "our," or "us") operates the Chicken Masterclass mobile application (the "App") and its companion website at egg0035.com. Like any good cookbook, we believe in clarity about every ingredient — and that includes the small handful of technical details the App needs to run. This Privacy Policy explains, in plain language, what information the App handles, why, and how we keep it secure. Everything we do here is in service of two goals: making the recipes work beautifully on your device, and making sure marketing and notifications are honest, useful, and respectful of your time.
By installing or using the App, you agree to the practices described below. We protect your information using industry-standard safeguards: all information transmitted between the App, our website, and our service providers travels over encrypted (HTTPS / TLS) connections, and we ask each provider to apply equivalent protections at rest.
The App is built around a simple principle: your kitchen is yours. Recipe photos, basket entries, streak progress, and personal notes never leave your device. The only data that does travel is a small set of technical signals needed to run the App, deliver notifications, and measure where new bakers discover us. Below, each item is named, explained, and tied back to the feature it powers.
Anonymous Installation Identifier. The first time you open the App, it generates a random identifier and stores it on your device. Think of it as a chef's name tag — it tells our service providers that messages and events belong to one installation, but it carries no personal information about you and is not tied to your name, email, or device account. Clearing app data or uninstalling the App resets it.
Device Language and Region. The App reads your device's language and region setting so it can pour content into the right language and so we can send notifications in a language you actually read. This is a system setting, not a tracking signal.
Local Recipe Data. Your basket, your streak, your daily Egg Wheel spins, your Crack & Combine results, your personal notes, and any photos you attach to a recipe are stored only on your device, in a small local database. None of this is uploaded to us, and none of it is shared with anyone. Tapping Delete All Data in Settings removes it; uninstalling the App removes it; clearing the App's storage in your device's system settings removes it.
Recipe Photo Notes (Optional). When you open a recipe and tap Camera or Gallery, the App asks your device's camera app to take a new photo, or asks your device's photo picker to let you choose an existing one. Your device may show a one-time permission prompt the first time you do this. The selected image is copied into the App's private storage on your device and attached to that recipe note. We do not transmit recipe photos to any server, and we do not access your camera or gallery in the background — only when you tap one of those buttons. You can revoke camera or photo access at any time from your device's app settings (Android: Settings → Apps → Chicken Masterclass → Permissions).
Built-in Browser. The App includes a built-in browser used to display this Privacy Policy and the Support page directly within the App. The built-in browser is a standard system component — like the one any other mobile app uses — and it supports cookies (including third-party cookies) and local site storage. Any websites loaded inside the built-in browser operate under their own privacy practices. The built-in browser does not collect additional information beyond what the App already collects (see above).
To know which channels are bringing new bakers into the App, we use a mobile attribution service (described in the next section). Two specific items below are the technical signals that service needs.
Advertising Identifier (Google Advertising ID). Android phones provide a resettable advertising identifier that the App reads on first launch. It is used solely for install attribution and fraud prevention — not for building advertising profiles within the App, which does not show ads. You can reset it or opt out of personalized advertising at any time under Android Settings → Google → Ads.
Install Attribution Data. When you install the App, our attribution partner receives a small amount of information about how you arrived at the Play Store listing — for example, which campaign or referral link led you there. This is used to measure marketing performance and to understand which channels are healthy. It is not used to identify you personally.
Yes — sparingly, and only with your permission. We may send notifications about new recipe drops, streak milestones, or noteworthy seasonal techniques.
Push Subscription Identifier. When push notifications are enabled, our notification provider (OneSignal — see the next section) generates a unique subscription identifier for your installation so it knows where to deliver a message. This identifier is associated with your device, not with your personal identity, and is reset if you clear app data or uninstall the App.
Language Tag. The App tells the notification provider which language your device is set to, so notifications arrive in a language you read.
Push notification permission is requested at runtime on Android 13 and later. You can deny the permission, or revoke it later under Android Settings → Apps → Chicken Masterclass → Notifications. If notifications are off, no push messages will reach you.
Support and Bug Reports. The App's Support page opens our website's contact form inside the built-in browser. You only ever provide information here when you choose to send a message. The form asks for:
This information is submitted only when you tap Send Message, and we use it solely to respond to your inquiry and resolve the reported issue. The App itself does not access your camera directly for support attachments — photo and video capture is handled entirely by your device's built-in camera app, which manages its own permissions.
To make attribution and push notifications possible, we share specific items with two carefully chosen service providers. Each one receives only the minimum it needs and is bound by its own published privacy policy.
AppsFlyer (Mobile Attribution). AppsFlyer helps us measure where new installs come from and detect fraudulent installs. We share with AppsFlyer the advertising identifier described above, the install attribution data (campaign, source, referrer), and the App's anonymous installation identifier. AppsFlyer also collects baseline device data such as IP address, device model, and operating system version as part of its standard operation. Privacy policy: https://www.appsflyer.com/legal/services-privacy-policy/.
OneSignal (Push Notifications). OneSignal delivers push notifications on our behalf. We share the subscription identifier and language tag described above. OneSignal additionally collects baseline device telemetry — device model, operating system version, carrier, app version, timezone, and an approximate country derived from your IP address — as part of its standard registration. Privacy policy: https://onesignal.com/privacy_policy.
We do not sell your personal information, and we do not share it with anyone other than the providers named above. Our service providers may process data in countries other than the one in which you reside, subject to appropriate safeguards required by applicable law.
You are always in charge of what stays on your device, what reaches our service providers, and what we hold on your behalf. The controls below are intentionally simple.
How long is data kept? Local recipe data, basket, streak, and photos persist on your device until you remove them with Delete All Data, clear the App's storage, or uninstall the App. The anonymous installation identifier persists for the life of the installation and is regenerated if you clear app data. The advertising identifier is managed by Google Play Services and can be reset by you at any time. The push subscription identifier is managed by OneSignal and is tied to your installation. Identifier data held by AppsFlyer and OneSignal is retained according to each provider's policy; we keep server-side identifier data only for as long as it serves the purposes described in this policy.
How can I clear or reset things? Tap Delete All Data in the App's Settings to remove your basket, streak, photos, and personal notes. Reset your advertising identifier under Android Settings → Google → Ads. Revoke notification permission under Android Settings → Apps → Chicken Masterclass → Notifications. Revoke camera or photo access under Android Settings → Apps → Chicken Masterclass → Permissions. Uninstalling the App removes all locally stored data.
Can I request deletion or access? Yes. Email [email protected] from the address you'd like us to look up, and we will help you exercise the rights available to you under applicable law — including access, correction, and deletion of any identifier-level data we may hold. Please mention "privacy" in the subject line so the message reaches the right team.
Children's Privacy. The App is intended for general audiences and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.
Changes to This Policy. We may update this Privacy Policy from time to time as the App grows or as service providers change their practices. The "Last Updated" date at the top of this page reflects the most recent change. Continued use of the App after changes are posted means you accept the revised policy — we encourage you to glance at this page when an update is announced.
How to Reach Us. If you have any questions, requests, or concerns about this Privacy Policy or our data practices, write to us at [email protected] or use our contact form. We aim to reply within two to three business days.
