About CryBaby: Know Why They Cry
Wondering why your baby is crying? CryBaby analyzes 10 seconds of crying to suggest possible reasons. AI can be wrong, so you get the top 3 candidates with confidence scores (%) rather than a single definite answer. [Record and explore] Tap record to detect crying and start recording automatically. Swipe through the top 3 results. The 9 categories: Tummy Ache, Burping, Hot/Cold, Uncomfortable, Hungry, Happy, Lonely, Scared and Sleepy. [Record or correct a result] Choose "Record this reason", "None of these is right" or "Skip rating", or select another reason to record. Your action is sent to the analysis server. [History and statistics] Recordings and results are saved on your device for playback and review. Explore recorded reasons, times of day and recording trends. These counts represent app recordings, not every time your baby cried. A dark night mode and large recording button make the app easier to use at night. [Free use and a one-time purchase] • One free analysis each day. Unused daily allowances do not carry over. • Complete a rewarded ad and receive its reward to add one analysis. These extra uses can be saved. • Ads may not always be available. • Buy "Unlimited analyses, no ads" once to remove analysis limits and ads. This is not a subscription. • Restore a previous purchase in Settings. [17 languages] Japanese, English, Simplified and Traditional Chinese, Korean, Spanish, French, German, Portuguese, Italian, Russian, Arabic, Hindi, Thai, Turkish, Urdu and Indonesian. [Data and privacy] Analysis requires internet access and audio upload. Our dedicated analysis server runs on Hugging Face Spaces, hosted by Hugging Face, Inc. We explain the destination and data, and upload only with your explicit consent. We send audio, a 16-character pseudonymous ID generated and saved on the device, recording time and your action on the result. We do not send names, addresses, email, phone numbers, contacts, precise location or raw IDFV to the analysis server. Network information such as IP addresses may be processed during communication. Transfers use HTTPS. Audio and result contents are not sold or used for advertising. With "Help Improve the AI" off, temporary audio on the server is deleted after analysis. With it on, audio is kept until you act on the result, then pseudonymized audio and your action are retained for AI improvement. There is no fixed maximum retention period for improvement data. "Exclude from statistics" requests deletion of server audio. Force-closing the app or a failed connection may prevent the request from reaching the server, leaving audio there. Change upload consent and "Help Improve the AI" in Settings > Privacy Settings. Disabling upload prevents new analyses; history on your device remains available. Settings > Delete AI Improvement Data lets you request deletion of improvement data for the pseudonymous ID currently saved by the app. Device recordings and history remain. Deletion cannot remove the data's influence from models already trained on it. We use Firebase Analytics for usage statistics and Google AdMob for rewarded ads. We do not send recorded audio or analysis result contents to these services. See Privacy Policy in the app for SDK identifiers and usage, advertising and diagnostic data. [Disclaimer] AI results are for reference, not medical diagnosis or a substitute for checking your baby's condition. Consult a medical professional if you notice a health concern. [Support] Use Contact in the app for questions or bug reports.
