Caption Coach AI — Privacy Policy
Last updated: June 5, 2026
Caption Coach AI (“the app,” “we,” “us”) is published by Sun Ventures. We built it to be private by default: no account, no sign-in, and no email required. This policy explains what stays on your device and the one place your content is sent to generate captions.
What's stored on your device
Everything you enter — your name, niche, default tone, voice samples (the posts you paste in), profile picture, your generated-caption history, and your settings — is stored only on your device using Apple's standard on-device storage. We do not keep a copy. Deleting the app, or using Reset in Settings, erases all of it.
How captions are generated
When you generate a caption, the app sends your request — your voice samples, the niche and tone you chose, and the topic you typed — to a processing service operated by Sun Ventures (a secure relay), which forwards it to Anthropic's Claude API to write the caption and return it to your device.
- This content is used only to generate your caption and return it to you. There is no account to tie it to, and we never use it to build an advertising profile or sell it.
- Your profile picture is never sent off your device — it stays local.
- Per Anthropic's API terms, content sent through the Claude API is not used to train Anthropic's models.
Purchases
Caption Coach Pro is an auto-renewing subscription. Transactions are processed by Apple, and we use RevenueCat to deliver and restore your subscription. This involves a purchase receipt and an anonymous device identifier, used solely to provide and restore your purchase — never for advertising or cross-app tracking.
Analytics & advertising
None. Caption Coach AI has no analytics, no advertising SDKs, and no third-party trackers.
Your choices & data deletion
Because there's no account, you control all of your data on your device. Use Reset in Settings, or delete the app, to remove everything. Since we don't keep an account or a copy of your captions, there's nothing for us to delete on our end.
Children's privacy
Caption Coach AI is not directed to children under 13 and does not knowingly collect personal information from them.
Changes
We may update this policy from time to time; the date above reflects the latest version.
