Egao is a personal wellness companion designed to help you reap the scientifically proven benefits of smiling (the facial feedback effect). The App provides automatic smile detection, daily streak tracking, smile statistics, on-screen affirmations, and customizable reminders to support positive habit formation.
100% On-Device Processing: Egao operates with privacy as a fundamental design principle. All machine learning inference (face and smile detection via LiteRT), timer calculations, streak counts, session logs, affirmations, and optional photos run strictly on your local device hardware. Egao requires no user registration, no account creation, and transmits zero facial data, video streams, or photos to external servers.
Egao is an informational and personal well-being logging tool only. It is NOT a medical device.
The App does not provide medical, psychological, psychiatric, or clinical advice, diagnosis, or therapy. Although smiling has scientifically documented associations with emotional mood elevation, stress relief, and psychological resilience, the App is neither designed nor intended to prevent, diagnose, monitor, treat, or alleviate any clinical illness, depression, anxiety disorders, or medical condition.
The App is not a substitute for professional healthcare, psychiatric evaluation, or medical advice. If you have concerns about your mental or emotional health, or if you are experiencing a mental health emergency, please immediately consult a qualified physician, psychologist, or healthcare professional, or contact your local emergency services.
To automatically detect and count your smiles, Egao requests access to your device's camera:
Transient Real-Time Analysis: The camera feed is analyzed frame-by-frame entirely within volatile device memory by on-device computer vision models. Camera frames are discarded immediately after smile classification and are never stored on disk unless you explicitly take or save a smile picture.
Optional Smile Pictures: If you choose to capture a smile picture during a session, the picture is stored exclusively within your local device storage. We do not build facial recognition profiles, we do not identify individuals, and we never transmit your images or camera data to any remote server or third party.
Your smile data belongs exclusively to you and remains on your device.
All your smile counts, session durations, daily streaks, personal best records, custom affirmations, reminder settings, and optional smile photos are stored locally on your device in a local database (SQLite) and app-specific directories.
Because your data is stored exclusively on your device and we do not host cloud accounts or mirror user data on external servers:
The free version of Egao displays third-party advertisements served via Google AdMob. Advertisements may use non-sensitive device identifiers subject to your privacy choices as described in our Privacy Policy.
Users may optionally purchase "Remove Ads" (egao_remove_ads), a one-time, non-consumable digital in-app purchase that permanently removes third-party banner and interstitial advertisements from the App on supported devices associated with your store account.
All in-app purchases are billed and processed directly through the Google Play Store (for Android) or the Apple App Store (for iOS), using the payment method linked to your store account. We do not collect, process, or store credit card numbers or banking credentials.
Pricing, billing, taxes (such as VAT or sales tax), and transaction receipts are handled directly by Google LLC or Apple Inc. in accordance with their respective storefront terms (such as the Google Play Terms of Service and Apple Media Services Terms).
Refund requests are subject to the policies of Google Play or the Apple App Store:
All rights, title, copyright, and intellectual property in and to Egao — including but not limited to the source code, machine learning classification pipelines, visual designs, icons, artwork, audio chimes, trademarks, and documentation — are the exclusive property of Dr. Bernhard Piskernik.
Subject to these Terms, we grant you a personal, revocable, non-exclusive, non-transferable, non-sublicensable, and royalty-free license to download, install, and use Egao on your mobile device strictly for personal, non-commercial purposes in compliance with these Terms.
You agree not to:
Egao is provided on an "AS IS" and "AS AVAILABLE" basis, without warranties of any kind, whether express, statutory, or implied.
To the maximum extent permitted by applicable law, we expressly disclaim all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, title, quiet enjoyment, accuracy, reliability, and non-infringement. We do not warrant that the smile detection will operate flawlessly under all lighting conditions, camera hardware, or angles, or that the App will be uninterrupted or completely error-free.
To the fullest extent permitted by applicable law (including Austrian and EU consumer protection regulations):
Nothing in these Terms limits or excludes liability for intent (Vorsatz), gross negligence (grobe Fahrlässigkeit), personal injury, or any statutory consumer rights that cannot be legally waived or excluded by contract under applicable law.
You may terminate your agreement with these Terms at any time simply by uninstalling and discontinuing all use of the App.
We reserve the right to modify, update, enhance, or discontinue the App or any part thereof at any time. When updates are published on the Google Play Store or Apple App Store, your continued use of the App will constitute acceptance of any updated functionality.
These Terms shall be governed by and construed in accordance with the laws of Austria, excluding its conflict of laws principles and the UN Convention on Contracts for the International Sale of Goods (CISG).
If you are a consumer residing within the European Union, this choice of law does not deprive you of the protection afforded by mandatory provisions of the law of your country of habitual residence. Consumers within the EU may also submit disputes to the European Commission's Online Dispute Resolution (ODR) platform at https://ec.europa.eu/consumers/odr.
We may update or revise these Terms from time to time. Any changes will be posted directly to this URL with a revised "Last Edited" date. We encourage you to review this page periodically. Continued use of the App after the posting of changes constitutes your acceptance of the revised Terms.
