Privacy Policy

This Privacy Policy explains what data captionrich (“we”, “us”) collects when you use captionrich.com and how we use it. We've kept it short and specific to what the product actually does.

1. Data we collect

Account information

When you sign in with Google, we receive your email address, name, and profile image from Google. We store this so we can identify your account and load your projects.

Usage data

We track the number of videos you've processed in the current billing period, how much of your plan's monthly AI allowance you've used, your subscription tier, and timestamps for account activity. This is required to enforce plan quotas.

Billing data

Payments are processed by Polar (polar.sh). We do not see or store your card details. We receive an external customer ID, your subscription status, and renewal/cancellation events from Polar so we can provision access correctly.

Your videos

Editing happens in your browser — uploading, transcribing, styling, and exporting all run locally on your device. Audio extracted from your video is sent to our transcription provider (see Section 3) only for the purpose of generating captions, then discarded.

If you choose to save a project to the cloud so you can resume it on another device, the source video and the assets it uses (B-roll, music, and images) are uploaded to and stored in Cloudflare R2 under your account. We keep your 5 most recently saved projects; saving a new project beyond that limit automatically deletes the oldest one's files. You can delete a saved project at any time, and deleting your account removes all of them. If you never save to the cloud, your video never leaves your browser.

Local browser storage

We use your browser's local storage to remember small conveniences like recent colors and recent translation languages. No personally identifying information is stored locally.

2. How we use your data

• To authenticate you and load your projects.
• To store and re-load projects you choose to save to the cloud.
• To enforce plan quotas (videos per month, video length, and your monthly AI allowance).
• To process subscription payments and respond to billing events.
• To send transactional emails (welcome, payment failure, cancellation receipts).
• To respond to support requests when you email us or use the in-app contact form.

We do not sell your data. We do not run advertising trackers on the site.

3. Third-party services

We rely on the following processors to run the service. Each handles only the data needed for its specific role:

• Cloudflare — hosting, database (D1) for accounts, usage, and subscription state, and object storage (R2) for projects you save to the cloud.
• Google — sign-in (OAuth), and on-device face-detection models (MediaPipe) loaded from a CDN for smart caption placement; the detection runs in your browser and your video is not sent to Google.
• Polar — payments, subscriptions, and the customer billing portal.
• Deepgram — primary speech-to-text transcription. Audio is sent for transcription and not retained for training.
• Groq — fallback transcription and a fallback provider for AI editing features.
• DeepSeek — the AI editing features (e.g. smart scenes, auto B-roll, emoji, motion graphics, remove bad takes, clips, and translation), only when you trigger them. Free-plan accounts don't use AI features.
• Pexels and Pixabay — stock video and image search for B-roll.
• GIPHY — GIF search.
• Resend — transactional email delivery.

4. Cookies

We use a small number of essential cookies to keep you signed in and to remember your session. We do not use third-party advertising or tracking cookies.

5. Data retention

Account, subscription, and usage records are retained for as long as your account is active. Cloud-saved projects are kept until you delete them or until they're evicted by the 5-project limit (oldest first). If you delete your account, we delete your account record and the related data linked to it from our database, and we wipe all of your saved videos and assets from Cloudflare R2. Account deletion isn't available while you have an active paid subscription — cancel it first, then delete. Aggregate, non-identifying billing records may be retained as required for accounting and tax purposes.

6. Your rights

You can request a copy of your data, ask us to correct it, or request deletion at any time by emailing support@captionrich.com. If you're in the EU/UK, you also have the rights afforded to you under GDPR / UK GDPR.

7. Children

captionrich is not intended for children under 13 (or 16 in the EU). We do not knowingly collect data from children.

8. Changes to this policy

If we make material changes to this policy, we'll update the effective date at the top of the page and, where appropriate, notify you by email.
