1. What this policy covers
This policy covers the Kiku Captions iPhone app and its use of KikuAI Automatic Subtitles. The general KikuAI Privacy Policy also covers account, payment, infrastructure-log, and website processing.
2. Data used for the requested service
- The video you choose, its speech audio, optional Protected Terms, caption preview, timed SRT, and rendered MP4.
- Your email address, one-time sign-in challenge, session, and shared KikuAI balance when you sign in for export.
- Account job records such as job ID, status, measured duration, quoted and spent credits, and timestamps.
- For Apple in-app purchases: transaction and product identifiers, purchased credits, purchase environment, refund status, and an opaque identifier linking the purchase to your KikuAI account.
KikuAI does not store the source filename, media, transcript text, Protected Terms, signed job ticket, or output bytes in account history.
Apple handles in-app payment. KikuAI does not receive your card details or Apple account password. Verified purchase records are used for balance delivery, recovery, and refunds, separately from product analytics.
3. Remote processing
The source video goes to KikuAI's Hetzner worker. Extracted speech audio and optional Protected Terms go through KikuAI's private OmniRoute to Groq Whisper for transcription. Selected Russian segments that need punctuation may go through the same private route to Groq Qwen for punctuation-only restoration.
4. Product analytics
The app may send privacy-limited product events such as app opened, video accepted, preview completed, sample completed, export completed, or job failed. These events may include duration, segment count, quoted credits, and output format. They do not include email, filename, file content, media, caption text, Protected Terms, tokens, or account identifiers. The app sends these events through a separate cookie-free connection and does not link them to a KikuAI account.
5. Retention and your choices
Server copies of the source, extracted audio, preview, SRT, and rendered MP4 are deleted automatically within 24 hours. Files saved or shared from the device remain where you place them until you delete them. You can stop an in-progress wait, remove local exports, sign out of the KikuAI account, or request account-data help by email.
You can start and complete account deletion inside Kiku Captions from the signed-in account menu. The app identifies this as the shared KikuAI account, sends a new email verification code, and requires an explicit confirmation. Deletion revokes all sessions and API keys, removes the account identity, and permanently forfeits unused credits. If you use the same email later, it creates a new zero-balance account; local videos and exports on the device are not removed automatically.
The 24-hour media limit does not apply to account balances and purchase records needed for refunds, fraud prevention, tax, and replay correctness. After deletion, only the minimal opaque purchase and credit transaction records may be retained where required, without keeping the deleted email attached.
6. Contact
For privacy, access, correction, or deletion questions, email support@kikuai.dev. Do not attach private video, captions, Protected Terms, one-time codes, or tokens.
