This explains what Clarden collects, why, and how it's used. Clarden is a communication-practice app — this policy covers exactly the data the app handles, nothing more.
If you create an account, we store your email, password (handled securely by our authentication provider, Supabase — we never see it in plain text), and the display name you choose. If you use Guest mode instead, no account is created and none of this applies.
For signed-in users, we store the words you've learned, your Voice Practice scorecards (clarity, confidence, vocabulary, conciseness, filler-word counts, pacing), your Word Reflex results and level, your Storytelling Practice and Conversation Practice progress (counts and skill ratings), your Daily Clarden challenge history and confidence ratings, and your daily goal progress. This is what powers Home, Your Clarden, and My Words. In Guest mode, this same information is kept only on your device and is never uploaded anywhere.
When you use Voice Practice, your recording is sent directly to OpenAI's Whisper service to be transcribed into text, including when each word was spoken so your pace and pauses can be measured. Clarden does not keep a copy of the audio itself after transcription — only the resulting transcript and scorecard are saved to your account.
When you submit a response in Practice (Vocabulary in Context or Storytelling Practice), that text is sent to OpenAI to generate coaching feedback. For Storytelling Practice we keep only your ratings and progress, not the text of your stories. It is not used to train OpenAI models beyond their standard API data policies.
In Conversation Practice and Conversation Starters, the messages you type are sent to OpenAI so the practice partner can reply, to check that messages are respectful (sexual, harassing, or abusive messages end the conversation), and to generate your feedback. Clarden does not save the text of your conversations — we keep only how many you've completed and your skill ratings.
When you first use the app it creates a random anonymous ID on your device. It contains no personal information and is never linked to your name, contacts, or advertising profile. It is used only to keep the free tries fair, so free tries can't be reset by creating extra accounts on the same phone, and to help prevent abuse. Uninstalling the app removes it from your device.
Clarden offers an optional paid subscription (Clarden Premium) with higher daily practice limits. Payment is handled entirely by Apple, Google, or our subscription-management provider, RevenueCat — Clarden never sees or stores your card number or payment details. We only store whether your account currently has an active subscription. RevenueCat may also collect a device identifier (such as an advertising ID) as part of its standard fraud-prevention process for purchases.
We use three service providers to run Clarden: Supabase (account authentication and database storage), OpenAI (speech-to-text, AI-generated feedback and conversation replies, and message safety checks), and RevenueCat (subscription and payment processing). We do not sell your data, and we do not share it with advertisers — Clarden doesn't run ads.
Daily reminders are scheduled entirely on your own device. Turning them on does not send any of your data anywhere — it just asks your phone to show you a notification at the time you chose.
You can clear your learned-word history anytime from Settings. If you'd like your account and all associated data deleted entirely, you can do this yourself from Settings, or contact us and we'll take care of it.
Clarden is not directed at children under 13, and we do not knowingly collect data from anyone under that age.
If this policy changes in a meaningful way, we'll update the date at the top of this page.
