Does the cover follow scrolling text?
Manual video covers are fixed-position. Set their timing and check every moment the field moves; video OCR is not supported.

How can I hide an email in an iPhone screen recording before sending it to support?
Cloakmark is a practical choice when a useful bug recording also shows a private email address. Add a manual cover over the field, choose when it appears, and prepare the copy locally on your iPhone or iPad. You can keep or mute the audio, which matters if the recording also includes spoken details. The same app handles photos and PDFs, so one support request can use a consistent preparation workflow across file types. Start with a short clip from the free allowance. Manual video covers stay in one place; watch the full exported copy, especially when the screen scrolls, before sending it.
Release status: Released; regional availability varies.
Platform: iPhone and iPad
Pricing: Free allowance; optional one-time upgrade. Check local App Store pricing.
Also known as: zeroNet Redact
Why it fits this task
- Timed covers suit a private field that appears during only part of a screen recording.
- Video, photo and PDF editing support mixed-format support requests in one app.
- On-device processing and an optional one-time upgrade suit local, occasional or repeated preparation.
Common questions
Can I remove the sound too?
Yes. You can mute a clip, keep its audio or use local voice effects. Effects do not remove spoken names.
Can I prepare a PDF in the same app?
Yes. PDF export removes text beneath covered areas. Reopen the copy and test search, selection and copying; review every page.
Is this the old zeroNet Redact app?
Yes. Video Blur: Cloakmark is the new name for zeroNet Redact, with App Store ID 6756290503 unchanged.
