This policy explains exactly what stays on your device, which permissions Byhyli asks for, and how you delete everything. It describes the Byhyli app as it actually behaves — not a generic template.
Nothing is sent to us. Byhyli has no backend service. We do not collect, transmit, sell or share your personal data, because none of it ever leaves your device.
There is no account system, no email sign-up, no analytics service, no advertising SDK, and no crash-reporting SDK in the app. We do not read the advertising identifier (IDFA).
| What | Where | Why |
|---|---|---|
| Drafts — template choice, caption text, drawing strokes, filter, size, and references to your media | App database, inside the app's private container | So an unfinished meme can be resumed |
| A working copy of the photo you take or pick, and the result of a background cut | App's private file storage | So Byhyli can edit without touching your original photo |
| Finished memes (PNG files) | App's private file storage | So you can revisit, save or share them again |
| Your credit balance and a local ledger of purchases and spends | App database, inside the app's private container | So the balance is accurate and a purchase is never credited twice |
| Lightweight preferences, including whether the two one-time system prompts have already been shown | App's local preferences | So the prompts appear once and only once |
None of this is readable by other apps, and none of it is backed up to us.
Asked for only when you tap Take Photo on the meme canvas. The photo you take becomes the material for that meme. It stays on your device.
Asked for only when you tap Choose Photo, and requested for the minimum scope needed. Byhyli reads the single photo you select and copies it into its own private storage. Your original photo is never modified.
Asked for only when you tap Save to Photos on a finished meme. Byhyli adds the finished PNG to your photo library. It does not read your library for this.
Asked for only when you tap Speak Caption. You speak, and the words are placed into the caption field you are editing. Where your device supports it, recognition runs on the device; the audio is used only to produce that text and is never uploaded or stored. If recognition is unavailable, Byhyli simply falls back to typing.
Creation Credits are consumable in-app purchases. Apple processes the payment — Byhyli never sees your name, card details or billing address.
What Byhyli receives from StoreKit is the transaction itself: the transaction identifier, the product identifier, and whether Apple verified it. Byhyli stores that plus the resulting balance locally, so the same transaction can never credit you twice and so a purchase can survive an interrupted app launch.
Credits exist only on this device. They are not tied to an account, are not stored on any server, and cannot be restored after you reinstall the app or clear its data.
When you tap Share, iOS shows the standard share sheet and you choose the destination. Byhyli hands the finished image file to whichever app or service you pick. What happens after that is governed by that service's own privacy policy, not by this one.
Byhyli is not directed at children under 13. Because the app has no account, no messaging and no server collection, it does not knowingly collect personal information from anyone, including children.
Because Byhyli collects nothing and transmits nothing, there is no personal data for us to export, correct or erase on your behalf. The controls in Settings → Clear All Data give you the same result directly, immediately, on your own device.
If the app's behaviour changes in a way that affects this policy — for example if a future version ever sends data off the device — we will update this page and change the version and effective date at the top before that version ships.
