FAQ

Quick answers.

Is Glow Diary free to use?

Yes. You can track up to 3 habits, take 3 progress photos, and get 1 AI skin analysis per week — completely free. Premium unlocks unlimited everything plus the ingredient scanner.

What does the AI actually do?

Two things. First, an on-device Vision engine analyzes your selfie for brightness, evenness, redness, smoothness, texture, hydration and pore visibility. Then GPT-4o reviews the result and writes you a short summary with concrete next steps.

Are my selfies uploaded somewhere?

Progress photos stay on your iPhone, full stop. AI analyses send the photo through our secure proxy for one round-trip — nothing is stored, and we don't run any user database.

Will it work in my language?

Glow Diary launches in 14 languages: English, Spanish, French, German, Italian, Dutch, Turkish, Arabic, Hindi, Indonesian, Japanese, Korean, Russian and Brazilian Portuguese.

Can I cancel anytime?

Yes. Subscriptions are billed by Apple — cancel any time from iPhone Settings → your name → Subscriptions. The lifetime plan is a one-time purchase with no renewal at all.

Is this medical advice?

No. Glow Diary is a tracking and skincare guidance app — not a medical device. For real skin concerns, please see a dermatologist.
