LONG IMAGE WORKSHOP
Privacy Policy
Updated: September 22, 2026
Scope
This policy explains how Hangzhou Tuyu Zhixing Technology Co., Ltd handles information in Long Image Workshop, on this website and through support. Local image processing, website visits, support email and store payments are separate contexts described below.
1. Images and on-device processing
The app processes images you select through the system picker for stitching, editing, text recognition, sensitive-information suggestions and export. These editing and recognition operations run on your device. We do not receive your original images or edited results through an image server we operate, or use them for advertising or model training.
2. Permissions and local storage
Import, saving and sharing use system pickers, photo-library authorization or system sharing. Declining these actions may prevent import or saving. Image copies, drafts, edited results, preferences and temporary exports may be stored in the app sandbox to support editing and sharing. You can remove source images from drafts. To remove all app data, use the system’s clear-data or delete-app function where available. Exported images and backups must be removed separately; offloading or retaining app data may leave copies behind.
3. Accounts, analytics and purchases
The current app does not require an account with us and does not integrate third-party advertising or behavioral analytics SDKs. Versions offering purchases use the relevant app store or platform payment service and handles product identifiers, order or transaction evidence, purchase status and local entitlement records to purchase, validate and restore access. The platform may process account and payment information under its own policy. We do not receive full card details or account passwords. System or store diagnostics and backups are managed through your platform settings.
4. Website and support
This website uses no advertising trackers, analytics scripts or tracking cookies. Hosting, DNS and network providers process necessary connection data such as IP addresses, request times and browser details to deliver and protect the site; operational logs may contain error information. Support email includes the email address, issue description, device/version details and attachments you choose to send. We use it to reply, troubleshoot and handle requests. Redact sensitive attachments; do not send passwords, verification codes or payment credentials.
5. Sharing and external services
Images may leave your device through actions you choose, such as sharing, saving to a destination or enabling system photo sync or backup. Those providers apply their own policies. We do not sell personal information. Support information is disclosed only to necessary service providers, with your authorization or where legally required. The website is hosted in Singapore and email is provided through Gmail, so support information you send and website connection data may be processed outside your country or region.
6. Retention and security
Local data stays according to app and device storage behavior until replaced, removed or cleared. In-app cleanup does not remove exported photos or backups. We retain support information only as needed to resolve requests, conduct necessary follow-up and meet legal obligations, then delete or anonymize it. We use reasonable access controls and transport protection, but no storage or transmission method is absolutely secure.
7. Your choices and rights
Manage permissions and backups in system settings, delete local and exported files, and stop using the app at any time. Contact us to request access, correction, deletion, withdrawal of consent or other rights under applicable law. We may request necessary verification to avoid unauthorized disclosure or deletion. We do not hold copies of your local images and cannot remotely recover or erase them.
8. Children and policy updates
Minors should use the app with a guardian’s guidance. We do not actively request children’s personal information. Guardians may contact us if a child sends inappropriate personal information to support. We will update this page for material changes and provide notice or seek consent as required by law.
