Hydra Solutions ("we," "our," or "us") builds and maintains the Pure Suite of minimalist Android utility and productivity applications.
Our core engineering philosophy is simple: Your data belongs strictly on your device. Every application in the Pure Suite is engineered to operate 100% locally and offline, with zero runtime or manifest permissions, zero analytics, zero tracking SDKs, and zero external servers.
We do not collect, transmit, store, share, or sell any personal data, usage telemetry, or device identifiers under any circumstances.
This unified Privacy Policy applies to all Android applications published by Hydra Solutions on the Google Play Store under the "Pure" brand prefix, specifically including:
(Note: Applications published under other brand prefixes that require explicit hardware permissions are governed by their respective separate privacy policies.)
All applications covered by this Privacy Policy declare zero permissions in their compiled Android application manifest (AndroidManifest.xml):
android.permission.INTERNET): Our Pure Suite applications cannot connect to the internet, communicate with remote servers, or transmit data off your device.android.permission.CAMERA): In PureQR, barcode and QR code scanning is performed without requesting camera permission from your device. Instead, PureQR utilizes the official Google Code Scanner API (GmsBarcodeScanner) provided by Google Play Services. When you initiate a scan, the camera stream is handled strictly within the isolated Google Play Services system process on your device; PureQR never accesses raw camera frames or hardware and receives only the final decoded barcode/QR string that you explicitly scan.READ_EXTERNAL_STORAGE / READ_MEDIA_IMAGES): When opening, importing, or saving files (such as .txt or .md notes in PureNote, daily schedules in PureDay, or scanning a QR code from an image via the Android Share Sheet in PureQR), our applications rely strictly on Android's built-in system Storage Access Framework (SAF) and System Intents. Our apps only process the specific file or text you explicitly choose to interact with.AD_ID).We do not require user registration, accounts, or sign-ins. We do not collect names, email addresses, phone numbers, IP addresses, or biometric data.
We do not bundle any third-party analytics, crash-reporting, or advertising SDKs (such as Firebase Analytics, Crashlytics, Google AdMob, or Meta SDKs). We have no visibility into how often you open our apps, what notes or tasks you write, or what QR codes you scan.
When you scan a QR code containing a web URL using PureQR, the app displays the decoded link locally on your screen for your review. If you explicitly choose to tap "Open in Browser" or share the content to another application, Android hands that request off to your default web browser or chosen external app. Once you leave PureQR, your interaction with any external website is governed solely by that website's and browser's respective privacy policies.
Our applications do not collect personal information from anyone, including children under the age of 13 (or the applicable age of digital consent in your jurisdiction). Because zero data is collected or transmitted, our apps comply fully with the Children's Online Privacy Protection Act (COPPA) and the EU General Data Protection Regulation (GDPR) provisions regarding minors.
Because Hydra Solutions operates within the European Union (Hungary) and adheres to a strict Zero-Data architecture, we act neither as a data collector nor a data processor of your personal information on any external server. You retain 100% ownership, access, portability, and deletion control over your files directly on your hardware device.
If we expand the Pure Suite to cover new zero-permission utilities or update this policy for legal clarity, we will update the "Last Updated" date at the top of this page. Our foundational commitment—that Pure Suite applications will never collect, track, or transmit your personal data—will remain unchanged.
