Longlight

Terms of Use

Version 1.0 · Effective date October 8, 2026

These Terms of Use constitute a legally binding agreement between you and the developer of Longlight (慢光). They govern your installation and use of the App and your access to and use of the Site. The English version is the controlling version.

1. Definitions

1.1 "App". "App" means Longlight (Chinese name 慢光, Bundle ID com.gacing.Longlight), the photography application for iPhone and iPad running iOS or iPadOS 18 or later, distributed through the Apple App Store, together with its software, code, interfaces, content provided by the Developer, and updates.

1.2 "Site". "Site" means the website at longlight.gacing.com, a subdomain of gacing.com, including its pages and content.

1.3 "Developer". "Developer" means the developer of the App, using GACING as the public signature on the Site and in copyright notices.

1.4 "you". "you" and "User" mean any natural person or organization that downloads, installs, or uses the App or accesses the Site. An individual using the App on behalf of a school, company, or other organization accepts these Terms on behalf of that organization, and "you" includes that organization.

1.5 "Apple". "Apple" means Apple Inc.

1.6 "Standard EULA". "Standard EULA" means Apple's Licensed Application End User License Agreement.

1.7 "User Content". "User Content" means the photographs, retained source frames, growth videos showing an image building up, reports, and exported files that you create through the App, including location metadata that you choose to include in photographs.

1.8 "Third-Party Services". "Third-Party Services" means services, software, system frameworks, infrastructure, and networks provided by parties other than the Developer, including Apple's services, hosting infrastructure, network services, and the services you choose for backups or sharing.

1.9 "Diagnostic Data". "Diagnostic Data" means the on-device rolling diagnostic log and capability report that you may choose to share from the App’s "Settings". The capability report describes the device model, operating system version, and camera capabilities. These diagnostic materials contain no photographs, location, or personally identifying information; information in an email you send with them is addressed separately in the Privacy Policy.

1.10 "Privacy Policy". "Privacy Policy" means the privacy policy for the App and the Site published on the Site, as revised from time to time.

1.11 "Terms". "Terms" means these Terms of Use, as revised in accordance with Section 16.

2. Acceptance and Scope

2.1 Acceptance. By downloading, installing, or using the App, or using the Site, after these Terms have been made available to you, you accept these Terms and acknowledge that you have read, understood, and agree to be bound by them. If you do not agree to any part of these Terms, you must not download, install, or use the App, must delete it from your devices, and must cease using the Site.

2.2 Applicability. These Terms apply to all Users, including persons who only access the Site and persons who use the App without accessing the Site.

2.3 Relationship to the Standard EULA. The copy of the App distributed through the App Store is licensed to you under the Standard EULA. These Terms supplement the Standard EULA with additional rules governing your use of the App and other agreements between you and the Developer. If these Terms conflict with the Standard EULA concerning that copy, the Standard EULA controls.

2.4 Privacy Policy. The Privacy Policy describes how the App and the Site handle data. It is an informational notice referenced by these Terms, but is not incorporated into them and does not form part of this agreement.

3. The App and the Site

3.1 What the App Does. The App combines multiple short-exposure frames on your device to produce long-exposure photographs. It provides the "Star Trails", "Light Trails", "Silky Water", "Light Painting", and "Night Scene" presets, together with "Manual" mode and "Test frame" assessment. It calculates astronomical time periods and moon phase offline in "Tonight". Capture tools include checkpoints every minute and interruption recovery, "Keep every frame", "Undo last minute", and exclusion of selected minutes using "Re-stack" with retained frames. Output options include HEIF, 16-bit TIFF, single-frame DNG on supported devices, and growth videos. The App also provides "Red interface", "Dark screen", and shutter operation using volume buttons, Camera Control, and Bluetooth remote shutters where the relevant controls are available.

3.2 On-Device Processing. Image capture and stacking take place on your device. The App establishes no network connections.

3.3 Free Use. The App is free of charge, with no in-app purchases or subscriptions. It is advertising-free and can be used without an account.

3.4 The Site. The Site provides information about the App, support information, these Terms, and the Privacy Policy. It is a static website and includes a beta installation page limited to registered devices.

3.5 Permissions and Optional Inputs. Camera access enables photography. The App requests only add-only access to Photos to save finished images to your photo library; "Save finished photos to Photos" is enabled by default and can be turned off in the App’s "Settings". The App does not read existing photographs in your library. Location is optional: it can be used for twilight and moon-phase calculations in "Tonight", for which you can instead enter coordinates manually. The separate "Write location into photos" setting is off by default and, when enabled, writes location into photograph metadata. Motion sensors are used only to display the level, without recording their readings.

3.6 Scope of the Developer. The Developer provides the App and the Site. The Developer has no access to App data on your device and cannot retrieve your works, checkpoints, or device backups. Information the Developer may receive or handle is limited to the categories described in the Privacy Policy: materials you choose to send, correspondence, Site connection data processed to deliver requested pages, and aggregate crash and usage statistics supplied by Apple through its own analytics-sharing mechanism.

4. License and Restrictions

4.1 App Store License. Your license to install and use the App Store copy is granted by the Standard EULA, as described in Section 2.3. These Terms do not grant a separate license to that copy. The restrictions in Section 4.2 supplement the Standard EULA.

4.2 Restrictions. Except as permitted by the Standard EULA or applicable law, you may not: (a) copy, modify, adapt, or create derivative works of the App; (b) decompile, reverse engineer, or disassemble the App, except to the extent such restriction is prohibited by applicable law; (c) rent, lease, lend, sell, redistribute, or sublicense the App; (d) remove, alter, or obscure copyright, trademark, or other proprietary notices; or (e) use the App in a manner prohibited by Section 12.

4.3 Reservation of Rights. The Developer reserves all rights not expressly granted. Breach of these Terms is subject to the remedies described in these Terms and applicable law. Termination of the App Store license is governed by the Standard EULA.

5. Eligibility

5.1 Age. You may use the App only if you have reached the age of legal majority in your jurisdiction, or if you use it with the consent and under the supervision of a parent or legal guardian who agrees to be bound by these Terms on your behalf.

5.2 Lawful Use. You represent and warrant that your use of the App and the Site does not violate any law, regulation, or order applicable to you.

5.3 Children. The App is not directed to children under the age of 13 (or any higher minimum age required by the law of your jurisdiction), and such children may not use the App.

6. Your Responsibilities

6.1 Permission to Photograph. You must obtain the consents and permissions required to photograph people, property, or protected material and to use the resulting images. You must comply with applicable privacy and photography laws and with the rules governing the places where you photograph.

6.2 Responsibility for Output. You are responsible for the capture, selection, use, storage, sharing, publication, and dissemination of User Content and for the consequences of those activities. This includes reviewing the content and metadata of files before sharing them. If you enable location metadata, recipients of the resulting files may be able to read that location.

6.3 Rights of Others. Rights in people’s likenesses, works, and other material you photograph remain with their respective rights holders. Use of the App does not transfer those rights to you or the Developer.

6.4 Prohibited Purposes. You must not use the App to photograph or monitor a person without legally required authorization, or to infringe anyone's privacy, intellectual property, or other rights.

6.5 Assessment of Results. You are responsible for deciding whether a photograph, "Test frame" assessment, calculated astronomical time, moon-phase indication, or other output is suitable for your intended use, as described in Section 8.

6.6 Devices and Resources. You are responsible for providing a compatible device and operating system and for managing the power, storage space, and physical conditions needed for a capture. Use a stable support where the intended photograph requires it, and operate the device and any shutter accessories safely.

6.7 Backups. You are responsible for backups of your works. Finished photographs (HEIF), previews, 16-bit TIFF files, work reports, and work information are included in system iCloud or computer backups according to your backup settings. The App marks retained source frames, growth videos, and recovery checkpoints as excluded from system backups. Checkpoints support recovery of an interrupted capture; they are not a substitute for backups of completed works.

7. User Content and Data on Your Device

7.1 Ownership. As between you and the Developer, you own your User Content, subject to the rights of others described in Section 6.3. The Developer neither claims nor requires a license to User Content stored on your device because the Developer cannot access it. Files you choose to send to the Developer are handled as described in the Privacy Policy.

7.2 Works and Backups. Finished photographs, previews, 16-bit TIFF files, optionally retained source frames, growth videos, work reports, and work information are stored in the App’s Documents directory and are visible in the Files app. Finished photographs (HEIF), previews, 16-bit TIFF files, work reports, and work information are included in system iCloud or computer backups according to your backup settings. The App marks retained source frames, growth videos, and recovery checkpoints as excluded from system backups. Copies in an iCloud backup are handled by Apple; computer backup copies are under your control.

7.3 Checkpoints and Diagnostics. Recovery checkpoints are stored in the App's Application Support directory, are created every minute during capture, and are excluded from backups. The App also keeps a rolling diagnostic log and a capability report on the device. You can choose "Share diagnostics log" or "Share capability report" under "Settings" › "Diagnostics" and select a destination for diagnostic materials.

7.4 Deletion. Deleting a work removes that work from the App's storage. Deleting the App removes its data on the device. The Developer cannot recover deleted data. These actions do not remove separate copies already saved to Photos, exported, shared, or included in backups. Manage those copies in their respective destinations.

7.5 Exports and Metadata. The App supports HEIF, 16-bit TIFF, single-frame DNG on supported devices, and growth videos. Once an item is exported or shared, its subsequent storage and handling are controlled by you and the destination you choose.

7.6 Capture Recovery and Editing. After an interruption, you can reopen the App to recover from a saved checkpoint. Recovery concerns the saved checkpoint and should not be treated as a guarantee that every moment before an interruption has been preserved.

8. Accuracy and Reliance

8.1 Photographic Output. A stacked photograph combines frames captured at different times. Movement, changes in light, device stability, capture settings, and camera capabilities affect the result.

8.2 "Test frame" and Astronomical Calculations. "Test frame" assessments assist your choice of capture settings. Twilight periods, other astronomical time periods, and moon phases are calculated offline using the relevant inputs, including optional location or coordinates you enter. They are planning aids, not observations of conditions at your location.

8.3 Reliance and Capture Conditions. The App is a photography tool. Its images, assessments, and calculations are not professional advice or a substitute for independent verification in decisions with significant consequences. Long captures can be affected by heat, battery level, available storage, and interruptions. Resource guards provide reminders and save capture progress when these constraints arise, but do not constitute a warranty that a capture will complete or that data will be recoverable.

9. Third-Party Services

9.1 Responsibility for Services. Third-Party Services are governed by their providers' terms and privacy policies. The Developer is not responsible for the acts, omissions, failures, or interruptions of those services, subject to applicable law.

9.2 Apple and Your Chosen Destinations. Apple provides the operating system, App Store downloads and account services, and iCloud backup services. Apple also administers the system option to share analytics with app developers. Services you select for sending diagnostic files, sharing works, or managing backups process the copies you supply under their own terms.

9.3 Website Hosting. The Site is hosted by DMIT in Los Angeles, California, United States, at longlight.gacing.com. The hosting provider and network operators may process technical connection data to deliver requested pages under their own policies.

10. Apple-Specific Terms

10.1 Parties. These Terms are entered into between you and the Developer only, and not with Apple. As between the Developer and Apple, the Developer, and not Apple, is solely responsible for the App and its content. The allocations of responsibility in this Section 10 are allocations between the Developer and Apple; they do not constitute any promise, representation, or warranty by the Developer to you.

10.2 Standard EULA. The relationship between these Terms and the Standard EULA is described in Section 2.3.

10.3 No Apple Maintenance or Support. Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the App.

10.4 Claims. As between the Developer and Apple, the Developer, and not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession or use of it, including (a) product liability claims; (b) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (c) claims arising under consumer protection, privacy, or similar legislation. As between the Developer and Apple, the Developer is solely responsible for the investigation, defense, settlement, and discharge of any claim that the App infringes a third party's intellectual property rights.

10.5 Third-Party Beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple has the right (and is deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

10.6 No Affiliation; Trademarks. Longlight is not affiliated with, sponsored by, or endorsed by Apple. Apple, App Store, iPhone, iPad, and iCloud are trademarks of Apple Inc., registered in the United States and other countries and regions.

11. Intellectual Property

The App, the Site, the Longlight and 慢光 names, and all software, text, graphics, and design provided by the Developer through the App or the Site, together with all associated intellectual property rights, are and remain the property of the Developer, protected under the copyright, trademark, and other intellectual property laws of the United States and under applicable international treaties.

11.2 Copyright Notice. © 2026 GACING. Ownership of User Content is addressed separately in Section 7.1.

11.3 Feedback. If you send the Developer suggestions, ideas, or feedback about the App or the Site, the Developer may use, modify, and incorporate them without restriction, attribution, or compensation to you.

Penal Code § 502, as well as comparable statutes of other jurisdictions. The Developer reserves all rights to pursue civil remedies and to refer matters for criminal prosecution under applicable law.

12.4 Consequences. Any breach of this Section may result in termination of your rights under these Terms and may subject you to civil liability and criminal prosecution under applicable law.

13. Disclaimers

15.2 Scope and Survival. This Section applies solely to claims brought by third parties. It does not shift costs or attorneys' fees between you and the Developer in a dispute between you and the Developer. This obligation survives termination of these Terms and your cessation of use of the App and the Site.

16. Changes, Suspension, and Termination

16.1 Changes to the App and the Site. The Developer may modify, suspend, or discontinue the App or the Site, or any feature or the distribution of them, in whole or in part, at any time and without prior notice.

16.2 Changes to These Terms. The Developer may revise these Terms at any time. A revised version takes effect upon publication on the Site, and material revisions are identified on the Site. Your continued use of the App or the Site following publication constitutes acceptance of the revised Terms. A revision does not apply to any dispute that arose, or of which the Developer was aware, before the revision took effect.

16.3 Termination by You. You may terminate these Terms at any time by ceasing all use of the App and the Site and deleting the App from your devices.

16.4 Termination by the Developer. The Developer may terminate or suspend your rights under these Terms at any time, for any reason (including breach of these Terms), and without prior notice, to the extent permitted by applicable law.

16.5 Survival. The provisions listed in Section 19.7 survive the termination of these Terms.

17. Export Control and Sanctions

17.1 Compliance. You acknowledge that the App and the technical data available through the App or the Site may be subject to the export control and economic sanctions laws and regulations of the United States, including those administered by the U.S. Department of Commerce and the U.S. Department of the Treasury.

18. Governing Law and Dispute Resolution

18.1 Governing Law. These Terms, and any dispute, controversy, or claim arising out of or in connection with the App, the Site, or these Terms (including non-contractual disputes or claims), are governed by and construed exclusively in accordance with the laws of the State of California, without regard to conflict-of-law principles or any choice-of-law rules that would cause the application of the laws of any other jurisdiction. Nothing in these Terms affects any mandatory consumer protection provisions of the law of your place of residence that cannot be excluded by agreement, and all provisions of these Terms otherwise apply to the maximum extent permitted by applicable law.

18.2 Exclusive Jurisdiction. Any legal action, suit, or proceeding arising under or relating to these Terms, the App, or the Site must be brought exclusively in the state or federal courts located in Los Angeles County, California. You irrevocably consent to the personal jurisdiction and venue of those courts and waive any objection to the exercise of personal jurisdiction over you and any defense of inconvenient forum or improper venue.

18.3 CLASS ACTION WAIVER. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, YOU AND THE DEVELOPER EACH WAIVE THE RIGHT TO PARTICIPATE IN A CLASS ACTION OR COLLECTIVE ACTION IN CONNECTION WITH ANY DISPUTE ARISING OUT OF OR RELATING TO THESE TERMS, THE APP, OR THE SITE. ALL DISPUTES SHALL BE RESOLVED ON AN INDIVIDUAL BASIS. IF THIS SECTION 18.3 IS FOUND TO BE INVALID OR UNENFORCEABLE, THIS SECTION 18.3 ALONE SHALL BE SEVERED, AND THE REMAINDER OF THESE TERMS SHALL REMAIN IN FULL FORCE AND EFFECT.

19. General Provisions

19.1 Severability. If any provision of these Terms is held by a court of competent jurisdiction to be invalid, illegal, or unenforceable for any reason, that provision shall be modified to the minimum extent necessary to render it enforceable or, if modification is not possible, severed from these Terms. The invalidity or unenforceability of any provision shall not affect the validity or enforceability of the remaining provisions.

19.2 No Waiver. The failure of the Developer to exercise or enforce any right or provision of these Terms shall not constitute a waiver of that right or provision. Any waiver is effective only if in writing and signed by the Developer.

19.3 Entire Agreement. These Terms constitute the entire agreement between you and the Developer concerning the App and the Site, and supersede all prior or contemporaneous understandings, agreements, representations, and warranties, both written and oral. With respect to the copy of the App distributed through the App Store, the Standard EULA also applies and prevails over these Terms as described in Section 2.3. The Privacy Policy is an informational notice describing data handling; it is referenced by these Terms but is not incorporated into them and does not form part of this agreement.

19.4 Assignment. You may not assign or transfer any of your rights or obligations under these Terms without the Developer's prior written consent. The Developer may freely assign these Terms at any time without notice.

19.5 Language. These Terms are drafted and executed in the English language. Any translation is provided for reference only. In the event of any conflict between the English version and any translation, the English version controls and prevails.

20.2 Deemed Receipt. Notices delivered by email are deemed received upon confirmation of successful transmission by the sender's mail server.

20.3 Non-Compliant Legal Notices. This Section 20.3 applies only to legal notices. The Developer is not obligated to respond to a legal notice that is not delivered in accordance with this Section, that does not contain sufficient information to identify the sender, the subject matter, and the legal basis of the notice, or that is not written in the English language. Requests made under the Privacy Policy, including requests for access or deletion, are not legal notices for purposes of this Section; the Developer accepts them in any language.
