1. Who we are
StitchSpan is provided by Shenzhen Xiaodangjia Technology Co., Ltd. This policy covers the iOS app, official website and support. For privacy questions, contact developer@typcb.cn.
The app requires no account and provides no developer cloud storage or sync. It contains no ads, third-party analytics or cross-app tracking SDKs. We do not sell personal information or use images or recordings for advertising profiles.
2. Processing on your device
Your selected images, videos, working copies, edits and stitching results are processed on your device and are not uploaded by the app to developer servers. Image matching, video frame extraction, cropping, annotation and export run locally. We do not write image contents or page text to ordinary logs.
The app stores language, appearance and export preferences locally, along with the names and settings of presets you save. Your language preference is shared locally with the capture and share extensions. Available disk capacity is checked only to determine whether processing can finish safely.
3. Photos, Files and screen recording
Manual import uses the system Photos or Files picker and receives only what you select. Recent Recording requests Photos read access to find the newest screen recording; limited access searches only authorized items. You can still select media manually if you decline read access.
Photos add permission is requested only when you choose to save to Photos. If declined, you can still export to Files or use the share sheet. iCloud or another file provider may download selected files first, under that service’s policies.
Control Center capture starts only after you confirm in the system broadcast interface and may include switching between apps. We keep system recording indicators, do not control other apps and do not bypass protected content. The capture extension saves no audio, and the app does not request microphone access. Review private content before recording and sharing.
4. Web capture and sharing
Web capture visits the address you enter or share and loads that page’s resources. The destination website receives network requests and may process IP addresses, cookies and other information under its own policies. The embedded browser uses an ephemeral session and does not automatically share Safari login state. Converting the page to an image happens locally.
The share extension receives only images, videos or web addresses you choose to share. It stores local copies for the app to import. Copies are removed after successful opening or import, retained after failure for retry, and can be deleted by swiping on the home screen. Files you send to other apps or cloud services are managed by your selected destination.
5. Retention, deletion and backups
The editing workspace is temporary. Working copies are cleared when you return home, leave the processing flow, clear the project or next launch the app. Export what you want to keep before leaving. Temporary exports are cleared on later exports, content edits, project clearing or the next launch. Copies already saved to Photos, Files or another app are unaffected.
Control Center recordings and task states are stored separately in local shared storage. You can process or delete them from the capture screen. Completed, canceled or failed tasks are cleaned up after more than seven days. Unprocessed or interrupted tasks remain for recovery or manual deletion. Active capture or processing tasks cannot be deleted. Deleting a capture does not remove the current editing copy or exported files.
Working copies, shared imports and capture files use system file protection and are excluded from system backups. Presets and preferences are stored separately; their backup behavior depends on device settings. Deleting an app differs from offloading it while retaining documents and data. We have no server copy of your media to restore and do not promise secure erasure of flash storage.
6. Pro purchases
Apple and StoreKit provide purchases, prices and restoration. The app reads verified product and transaction status to determine Pro access. We do not receive payment-card details or ask for your Apple account password. Product loading, purchase and restoration communicate with Apple’s store services; images and recordings are not uploaded as part of that process.
After a refund or revocation, new advanced operations require valid access. This does not itself delete exported files, existing projects or presets. Temporary workspaces still follow their normal cleanup lifecycle. Restoring purchases restores access, not media.
7. Website visits and support email
This website uses Cloudflare Pages for delivery and security. Cloudflare processes information needed to provide network services, such as IP addresses, request URLs, times and browser information. We add no behavioral analytics, advertising scripts, user accounts, forms or tracking cookies to the site. See the Cloudflare privacy policy for its network processing.
The app does not preload policy pages. It connects only when you open an online link, without adding your images, recordings, filenames or purchase history to that link.
When you email support, we receive the email address, description and attachments you choose to send. We use them to respond and investigate, retaining them as needed to handle the issue and meet applicable legal requirements. Avoid sending private images, complete recordings, passwords or payment credentials.
8. Your choices, children and changes
You can change system permissions, delete captures, shared imports and presets in the app, and manage exported files yourself. To request access, correction or deletion of support information we hold, or exercise other rights under applicable law, contact developer@typcb.cn. We will reasonably verify and address requests. Data held only on your device must be managed there.
The app is not designed to collect personal information from children. Minors should record, share and purchase with appropriate guardian guidance. Contact us if a child has sent support information that should not be retained.
If our processing changes, we will update the date on this page and appropriately communicate significant changes. We will seek consent where required. This policy does not replace the policies of Apple or third-party services you choose to use.
