# Frequently Asked Questions _Your questions about genetics, predictions, pregnancy tracking, privacy, and more - answered._ - Source: https://proba.baby/en/faq - Language: English - Last verified: v1.0.4 · 7 Sep 2026 ## General Questions **What is ProbaBaby?** ProbaBaby (listed on the App Store as “Pregnancy & Baby Tracker - PB”) is a free iPhone, iPad and Apple Watch app for pregnancy, newborn and postpartum tracking, built for twins, in 32 in-app languages, with an optional AI baby-face prediction that computes Mendelian genetics (Punnett squares) from the traits you enter before any image is generated. Tracking, tools, PDF reports and family sharing are free; only AI predictions use credits — 5 starter credits cover your first Scientific prediction — and no subscription is required. Requires iOS 26 or later. Not available on Android. **How is ProbaBaby different from other baby prediction apps?** Unlike apps that simply blend parent photos, ProbaBaby calculates genetic probabilities using real scientific models - including Punnett squares, dominant/recessive genes, and polygenic inheritance - before generating AI visualizations. **Are the predictions accurate?** Predictions compute trait probabilities in code with Punnett squares before any image is generated, so the percentages come from inheritance models rather than from blending photos. The confidence figure (60–95 %) reflects how complete your inputs are; it is not an accuracy measurement and is capped at 95 % by design. Predictions are for entertainment and education. ProbaBaby is not medical advice and not a medical device. **Is ProbaBaby a medical app?** No. ProbaBaby is for entertainment and educational purposes only. It is not a medical or diagnostic tool. Always consult healthcare professionals for medical advice. ## Credits & Pricing **What are credits?** Credits are the currency used for AI-powered predictions. Different prediction modes require different amounts of credits: Standard Mode (8), Premium Mode (12), and Scientific Mode (4). **Do credits expire?** No! Credits never expire. Buy once, use anytime. **Do I get any free prediction credits?** Yes — every new account gets 5 starter credits, enough for one free Scientific prediction (4 credits). After that, buy a credit pack whenever you want more; credits never expire. **Are there subscriptions?** No subscription is ever needed. Predictions run on credits, and nothing else in the app is paywalled. Seedling, Bloom and Blossom are optional Supporter subscriptions (Seedling monthly only; Bloom and Blossom monthly or yearly). They unlock no features and give no discount — they keep the app free and independent and are recognised with badges and the Supporter Wall. ## Genetics & Science **What genetic traits do you analyze?** We analyze eye color (2-gene model), hair color and type, skin tone (polygenic), height, and facial features including face shape, nose shape, dimples, and freckles. **Why do you ask for grandparent information?** Grandparent data helps us detect hidden recessive genes — for example, a brown-eyed parent might carry a recessive blue-eye allele from their own parent, which could appear in their child. Premium predictions are the ones that ask for all four grandparents; Standard and Scientific work from the two parents alone. **What are Punnett squares?** Punnett squares are a genetic tool that shows all possible gene combinations from two parents. We use them to calculate the probability of each trait appearing in your baby. **How does three-generation analysis work?** By inputting traits from all four grandparents, we can trace genetic inheritance patterns across generations and identify recessive genes that might otherwise be hidden. ## Privacy & Security **What happens to my photos?** Parent photos are used only to run your prediction and are deleted from our servers a few hours after it finishes — never before the prediction completes, and at least 4 hours after upload. The prediction itself — the report and the generated images — is removed from your account after 48 hours by default; you can choose 24 hours, 7 days or 30 days in Settings. Scientific mode sends no photos at all. **Is my data sold to advertisers?** Absolutely not. We never sell your personal data. Your genetic information and photos are used solely for generating your predictions. **How is my data protected?** Your data is encrypted in transit, with iOS data protection at rest on your device; photos are processed in private, access-controlled storage and are deleted a few hours after your prediction. You can delete your account from inside the app (the policy commits to removing personal data within 30 days) and export your account data — the rights GDPR describes, access, export and erasure, are open to everyone who uses ProbaBaby, wherever you live. We run no advertising, attribution or product-analytics SDKs, and we never sell data. **Can I delete my data?** Yes — delete your account directly in the app (Profile → Delete Account), behind a two-step confirmation. Your data is then removed from our servers under a 30-day policy window. You can also email privacy@proba.baby. ## Features & Platform **Does ProbaBaby work on Apple Watch?** Yes! ProbaBaby includes a full Apple Watch app for tracking kicks during pregnancy, and logging feeding, sleep, and diapers during postpartum - perfect for 3am feedings when you don't want to reach for your phone. **What widgets are available?** We offer 17 Home Screen and Lock Screen widgets — pregnancy week progress, due date countdown, baby size, kick counter, feeding timer, sleep tracker, diaper count, the 24-hour baby day clock and more — plus 8 Live Activities with Dynamic Island for real-time tracking on your Lock Screen, and 7 Apple Watch complications. **How many free tools are included?** 32 free in-app tools in 7 categories (genetic predictions, pregnancy health, fertility planning, baby names, baby development, labor preparation, postpartum care). None of them need credits or a subscription. **What languages are supported?** ProbaBaby supports 32 languages including English, Spanish, French, German, Italian, Chinese (Simplified & Traditional), Japanese, Korean, Portuguese (Portugal & Brazil), Russian, Serbian, Thai, Arabic, Hebrew, Greek, Turkish, Vietnamese, Polish, Romanian, Ukrainian, Indonesian, Malay, Filipino, Danish, Finnish, Norwegian, Swedish, Czech, Hungarian, and Dutch. We also have full RTL (right-to-left) support for Arabic and Hebrew. ## Pregnancy & Baby Tracking **What can I track during pregnancy?** Track your entire pregnancy journey: week-by-week progress, kick counting, weight monitoring, baby size comparisons, health metrics, symptoms, and appointments. **What's included in postpartum tracking?** Comprehensive tracking for both baby and mom: feeding (breast/bottle with duration), sleep logging, diaper changes, growth charts, milestones, mood tracking, EPDS screening, recovery progress, and hydration. **Does ProbaBaby support twins and multiples?** Yes. Mark twins or triplets on your pregnancy profile to get delivery-window guidance adjusted for multiples in your doctor visit summary, twin-specific weight-gain targets, and a hospital bag checklist that scales baby items to your baby count. After birth, every baby gets their own independent feeding, sleep, diaper, growth, and vaccination tracking - there is no limit on babies, and adding them is always free. **Are there birth preparation features?** Yes! Hospital bag checklists (for mom, baby, partner, and documents), birth plan creator, contraction timer with 5-1-1 rule alerts, and emergency contact management. **What fertility tools are available?** Ovulation calculator, fertility window tracker, cycle length calculator, conception date estimator, implantation timeline, plus fun predictors like Chinese and Mayan gender calendars. --- ProbaBaby (listed on the App Store as “Pregnancy & Baby Tracker - PB”) is a free iPhone, iPad and Apple Watch app for pregnancy, newborn and postpartum tracking, built for twins, in 32 in-app languages, with an optional AI baby-face prediction that computes Mendelian genetics (Punnett squares) from the traits you enter before any image is generated.
