Privacy Policy — ConverterKit

Last updated: 20 September 2026

ConverterKit does not collect any data.

That is the whole policy. The rest of this page explains what that means precisely, because "we don't collect data" is a sentence many apps write while collecting data.

What is collected

Nothing. ConverterKit has no account, no server, no analytics, no advertising, no crash reporting and no trackers. There is no database anywhere holding anything about you, because there is nowhere for one to be.

Apple's App Store listing for this app carries the "Data Not Collected" label, which is the same statement in Apple's words.

What happens to your files

Files you convert are read, converted and written on your iPhone, by Apple's own frameworks. They are never uploaded, and nothing about them — not the file, not its name, not its size, not its contents — is transmitted anywhere.

Converted files are written to Files › On My iPhone › ConverterKit and stay there until you delete them. ConverterKit never deletes them for you, and never copies them anywhere else unless you share them, or have Photos saving switched on.

Conversions keep metadata by default, because silently discarding it is a decision that should be yours. A converted photo keeps its camera details, date and location. A converted video keeps its location; its camera details and original capture date are not carried across by the system frameworks that perform the conversion.

One loss is not a choice and should be said plainly: converting a video to MP4 drops the camera make, model and the original capture date, because the MP4 format has nowhere to store them. The location survives, because MP4 does have a field for it. Photos are unaffected — an image carries its metadata across every format this app writes.

The Remove metadata tool strips this when you ask it to, for photos and for video, with a choice of removing the location only or removing everything. In both cases the picture is copied rather than re-encoded, so removing a location costs no quality.

It does not apply to audio or PDFs.

What the app can access on your device

• Your photo library — adding only. ConverterKit can add converted images and videos to your library: when you tap Save to Photos, or on every conversion if you switch that on in Settings. It is off unless you turn it on, and it covers images and video only — a PDF or an audio file cannot be added to a photo library at all. ConverterKit cannot read your library. The photo picker runs in a separate process managed by iOS, hands over only the items you select, and requires no permission.
• Files you choose, while converting them. Access is granted per file by iOS and ends when the conversion does. Nothing else on the device is visible to the app.

ConverterKit requests no other permissions. It does not ask for your location, your contacts, your microphone or your camera, and cannot access them.

Network connections

ConverterKit makes one kind of network connection: to Apple's App Store, to check whether ConverterKit Pro has been purchased and to complete a purchase if you make one. That exchange is between you and Apple. The developer receives no personal information from it and cannot see who bought the app.

There are no other connections. The app works fully in Airplane Mode, apart from buying or restoring Pro.

Purchases

ConverterKit Pro is a one-time purchase handled entirely by Apple. Payment details are never seen by, or available to, the developer. Whether Pro is unlocked is stored only on your device.

Third-party code

ConverterKit uses one third-party library: LAME 3.100, which encodes MP3 because iOS can decode MP3 but not create it. LAME runs on your device, makes no network connections, and receives no information about you. It is used unmodified under the GNU Library General Public License version 2, and is linked dynamically so it can be replaced. Its full licence text is in the app, under Settings › Open-source licences.

Everything else in ConverterKit is Apple's own frameworks or code written for this app.

Children

ConverterKit collects nothing from anyone, of any age, and contains no advertising, no external links to user-generated content, and nothing to sign up for.

Changes to this policy

If this ever changes, the change will be described here with a new date, and — because the change would have to be a change in the app's behaviour — in the app's release notes.
