- 关于个人隐私与设备权限调用的详细规范,请参阅我们配套的《隐私保护政策》。
三、用户行为守则与内容合法性保证
用户使用本软件处理、编辑、转换或导出的任何图片、文字与素材,应保证遵守所在国家与地区的法律法规:
- 合法版权保证:您保证对使用本软件所导入、处理的图片拥有完全独立的著作权、肖像权,或已获得合法权利人的完整授权许可;
- 合规使用禁令:严禁利用本软件制作、修改、合成、编辑或传播包含下列内容的图像或媒体:
• 反对宪法确定的基本原则、危害国家安全、泄露国家秘密、颠覆国家政权、破坏国家统一的;
• 含有暴力恐怖、淫秽色情、赌博传销、侮辱诽谤或侵犯他人隐私权、名誉权、肖像权的;
• 仿冒、伪造国家机关公文、印章、证件、发票、货币等涉嫌违法犯罪的;

• 违反法律法规、公序良俗或社会公德的其他内容。
- 违规后果自负:用户因违反本条规定导致的一切法律责任、行政处罚或对第三方的民事赔偿责任,均由用户自行全额承担。
四、技术限制与免责声明(Disclaimers)
重要免责提示:在适用法律允许的最大范围内,开发者对以下情形不承担连带责任:
- 原图备份建议:图片压缩(尤其是有损压缩与目标大小限制模式)会涉及不可逆的色彩空间量化与高频细节压缩。我们强烈建议您在对重要照片执行有损压缩或覆盖操作前保留原始文件的独立安全备份。用户因自行误删、覆盖原图或设置过低质量导致的文件损害,平台概不承担赔偿责任。
- 硬件性能与内存限制:图像算法的运行耗时与体验高度依赖于用户设备自身的芯片算力、GPU 加速支持与空闲物理运存(RAM)。在处理超大分辨率(如数千万至上亿像素原图)时,若因系统内存不足(OOM)导致闪退或耗时延长,属于硬件物理限制范畴。
- 不可抗力与系统兼容性:因操作系统异常崩溃、设备断电、存储介质物理损坏、恶意软件感染等第三方不可抗力因素造成的本地任务中断或数据丢失,开发者不承担赔偿责任。
五、知识产权声明
- 应用软件著作权:本软件的代码架构、UI 交互设计、算法集成、软件图标、商标标识及所有文档资料的知识产权均归 鲁班研发团队(Flutter Luban Team / CMXC)所有。未经书面许可,任何人不得对本软件进行反编译、逆向工程、反汇编、脱壳、篡改软件核心签名或制作衍生盗版版本。
- 用户生成物版权:用户使用本软件处理、编辑或创作生成的最终成果图片,其全部著作权与知识产权归属于用户本人或合法权利人所有,开发者不对用户作品主张任何版权份额。

2. Local-First & Zero-Cloud Guarantee
- Offline Processing: All pixels, raster operations, and compression streams are handled solely within your local hardware RAM and private app sandbox. We transmit no images over the internet.
- Data Sovereignty: History records and preferences reside strictly on-device. You can clear temporary caches and history logs anytime via Settings.
- For full privacy terms, please refer to our Privacy Policy.
3. Acceptable Use & User Warranties
You agree to comply with all applicable local, national, and international laws when using this application:
- Copyright Warranty: You warrant that you own or possess valid licenses, permissions, and rights to all images imported and processed.
- Prohibited Conduct: You agree NOT to use this software to create, modify, or distribute:
• Content that infringes copyrights, trademarks, privacy rights, or likeness of any third party;
• Defamatory, fraudulent, obscene, sexually explicit, hate-inciting, or terroristic materials;

- Indemnification: You assume full legal responsibility for any claims or damages arising from your misuse or unlawful manipulation of content.
4. Disclaimers & Technical Limitations
Important Technical Disclaimer: To the maximum extent permitted by applicable law:
- Backup Recommendation: Image compression (notably lossy modes and aggressive size constraints) inherently performs irreversible quantization. We strongly urge you to maintain independent backups of critical raw photographs prior to compression. We are not liable for accidental overwrites or quality degradation resulting from user-configured parameters.
- Hardware Constraints: Processing throughput is conditioned by your device's CPU/GPU capabilities and free memory. Ultra-high-resolution images (e.g. 100MP+) may require extended processing time or encounter OS memory limits.
- Force Majeure: We are not responsible for interrupted tasks or data loss stemming from unexpected OS crashes, power loss, or storage hardware failure.
5. Intellectual Property Rights
- Software IP: All source code, algorithm implementations, UI layouts, icons, logos, and documentation are proprietary assets of the Flutter Luban Development Team (CMXC). You may not reverse engineer, decompile, crack, or distribute pirated modifications.
- Your Creations: All rights, title, and ownership of the output images generated by you remain entirely with you. We assert no ownership or licensing claims over your images.
6. Minors
Minors should access this application under parental or guardian supervision. Guardians are responsible for advising minors on digital security and respect for copyright laws.
7. Modifications to Terms
We reserve the right to revise these Terms of Service. Any amendments will be reflected on this page. Your continued use of the application subsequent to updates constitutes acceptance of the modified Terms.
8. Governing Law & Dispute Resolution
These terms shall be governed by and construed under the laws of the People's Republic of China, without regard to conflict of law rules. Any dispute arising from these Terms shall first be resolved through friendly consultation; failing that, either party may submit the dispute to the competent people's court in the developer's domicile.
