App<\/strong>: Certifica AI (Android package Certifica AI offers free practice exams for artificial intelligence and cloud certifications (Microsoft, AWS, Google Cloud, NVIDIA, Databricks, Salesforce, Anthropic and Oracle). The questions are original study material written from each exam’s public objectives. The app is not affiliated with, endorsed by, or sponsored by<\/strong> any of these companies, and its practice exams and certificates are not official certifications<\/strong>. All trademarks belong to their respective owners. The same content is available on the web at certifica.ai.eti.br<\/a>.<\/p>\n The app has no accounts and no sign-in<\/strong>. We do not ask for and do not collect your email, phone number, address, precise location, contacts, photos or files. We do not track you across other apps or websites.<\/p>\n When you finish a practice round, the app sends our server at Each time the app is opened it sends our app statistics server ( The free version of the app displays a banner ad and, between screens, full-screen ads. These are served by the Google AdMob SDK, which may access your device’s advertising identifier (AAID) to serve relevant ads and measure performance. This identifier is controlled by Google and can be reset or limited by you at any time in your Android settings (Settings → Google → Ads<\/em>). See Google’s policy at policies.google.com\/privacy<\/a>.<\/p>\n These stay on your device only<\/strong> and are never sent to us:<\/p>\n The result certificate image is created on your device. It only leaves the device if you choose to share it, and then it goes to the app you pick (for example WhatsApp or LinkedIn) under that app’s own policy. Uninstalling the app deletes all local data.<\/p>\n If you purchase the optional ad-free upgrade, Google Play Billing processes the transaction. We only receive confirmation that the purchase is active. We never see or store your payment card information<\/strong> — all payment data is handled exclusively by Google Play.<\/p>\n Links to official study material (for example Microsoft Learn or AWS documentation) open in your device’s browser. Those sites are governed by their own privacy policies.<\/p>\n We do not sell your data, and we do not share it with anyone else.<\/p>\n Local data stays on your device until you uninstall the app or clear its data. Anonymous practice results and usage records are kept for statistics; because they are tied only to a random installation ID, they cannot be linked to you. Server access logs are kept only as long as needed for security and troubleshooting.<\/p>\n The app is not directed to children under 13 and we do not knowingly collect data from them.<\/p>\n All communication between the app and our servers uses HTTPS.<\/p>\n If a future version introduces new data collection, this policy will be updated before that version is released, and the “last updated” date above will change.<\/p>\ncom.certificaai.app<\/code>)

2. Data we collect<\/h2>\n
2.1 What we do NOT collect<\/h3>\n
2.2 Anonymous practice results<\/h3>\n
certifica.ai.eti.br<\/code> an anonymous record of that round: the exam code, the mode (study or exam), the question language, the score, the number of correct answers per exam domain, and a random installation ID<\/strong> generated by the app (it is not your advertising ID, is not linked to your identity, and changes if you reinstall). Our server also notes the country of the request, as reported by our network provider, and keeps only a one-way hash of the IP address, never the IP itself. We use this only for aggregate statistics, such as which exams are practiced most and which domains people find hardest, to improve the questions.<\/p>\n2.3 Anonymous usage count<\/h3>\n
myapps.ai.eti.br<\/code>) a small anonymous record with the same random installation ID, the app version, and whether the ad-free purchase is active. If you buy the ad-free upgrade, a one-time “purchase” event with the product name is also sent. This lets us count active devices and keep the app working well. It contains no name, account or contact information.<\/p>\n2.4 Advertising identifier (Google AdMob)<\/h3>\n
