Service Description
Back Pro is a tool for creating phone back plate and back sticker designs and exporting print-ready files. The app provides device selection, canvas editing, live preview, PNG/PDF export, local history restore, and optional AI sticker features.
Back Pro Lifetime
Back Pro Lifetime is a one-time non-consumable in-app purchase with product ID com.richeng.backpro.lifetime. It unlocks unlimited AI sticker generation, watermark-free PNG/PDF export, and future Lifetime features released within this same Back Pro app.
Lifetime is not a subscription and does not auto-renew. Price is shown by the App Store in your local currency.
Free Experience
The free version includes full basic editing, preview, history, and export, plus 3 successful AI sticker generations. Cancelled selections, failed processing, no-subject results, or unsupported devices do not consume a free use.
Free exports may include a Back Pro watermark.
Restore Purchase and Family Sharing
You can use Restore Purchase in Settings to check the App Store purchase history for the Apple Account signed in on your device. Use the same Apple ID you used to purchase.
Back Pro Lifetime supports App Store Family Sharing. Eligibility and sharing scope follow Apple Family Sharing rules.
Refunds and Revocation
Purchases, refunds, and billing disputes are handled by the Apple App Store. To request a refund, use Apple’s official channels. If Apple revokes a purchase, the app may remove the corresponding Lifetime unlock state.
Your Content and Responsibility
You are responsible for designs you create, images you import, and files you export. Ensure you have rights to use imported content and comply with applicable laws. Back Pro does not host or custody your design content on its servers.
Disclaimer
Back Pro is provided “as is.” We do not guarantee that exported files will produce identical physical results on every printer or material. Test print before bulk production.
