1. The service
These terms apply to the ColmapView website maintained by OpsiClear LLC. By using this website, you agree to these terms and the applicable terms of any external provider you connect. The privacy policy describes how data is handled.
ColmapView is a browser tool for inspecting and exporting COLMAP reconstructions and related images, masks, point clouds, and Gaussian splats. Google Drive and Hugging Face features are optional and available only in deployments where they are configured.
2. Your content and rights
You retain your rights to datasets and other content you load or publish. Loading content into the viewer does not transfer ownership to OpsiClear LLC or grant us a license to use it for unrelated purposes.
Use only files and accounts you are allowed to access. Before sharing or publishing, ensure you have the necessary rights and permissions for the reconstruction, photographs, identifiable people, locations, embedded metadata, masks, splats, and preview images. Select a dataset license only if you are authorized to grant its permissions.
Keep backups of your source files. Edits and exports can change reconstruction data; review exported results before using them elsewhere.
3. Connected accounts and providers
Signing in authorizes the account actions described by the consent screen and the viewer. You can disconnect from the viewer or revoke authorization through the provider. Providers control account eligibility, quotas, sharing rules, storage, and availability; their terms also apply.
Protect your provider account and device. Do not share authorization tokens. A private viewer link does not itself grant access to the underlying private dataset.
4. Publication and sharing
When you start a publication, you direct the app to transfer the dataset files and selected metadata to the chosen provider. The publication can include source photos and their embedded metadata, matched video frames, viewer settings, and a preview. For video-backed views, exported images use the manifest’s fixed frame selection while source recordings stay at their original host. A dataset read from one provider can be copied to another provider through this action.
Hugging Face publication creates a public dataset repository by default, with a Private option. Google Drive publication creates a ZIP shared with anyone with the link by default, with a Private option. Bucket uploads follow the bucket's existing permissions. Review the destination, license, and sharing choice before starting.
Where Spatial Hub is enabled, each upload also creates a Hub link whose card shows the title, description, preview and dataset link to anyone with the link. Hub cards are content you publish and are your responsibility. OpsiClear LLC may remove cards that break these terms or the law. Send removal requests to info@opsiclear.com.
Share on Hub separately asks you to make a public dataset and its metadata discoverable in the Hub catalog. Submit only content you have the right to share and describe its license accurately. Source checks or operator approval do not grant rights or guarantee complete loading. Submissions can remain pending or be rejected; removal requests can include the listing link or submission ID.
Public or link-accessible files may be copied by others. Cancellation, connection loss, or an error can leave provider-side files or repositories. Closing a dialog or disconnecting does not delete those copies. You are responsible for reviewing provider-side results and changing access or deleting unwanted copies through the provider.
5. Responsible use
Do not use the website to violate applicable law, infringe other people's rights, bypass access controls, distribute malicious files, or interfere with the website or connected services. Follow the source dataset's license and the rules of each provider.
Use the public issue tracker for reproducible, nonsensitive bug reports. Send private data, account, privacy, or security concerns to info@opsiclear.com.
6. Availability and results
The viewer is under active development. Features, file support, performance, and provider integrations can change or become unavailable. Browser capabilities, dataset size, source files, and third-party services can affect loading, rendering, export, and publication.
The website is provided as available, without a promise of uninterrupted operation or error-free results. It is not a certified measurement or safety decision tool. Independently verify results where accuracy matters. Nothing in these terms removes rights or protections that applicable law does not allow to be waived.
7. Open source software
The ColmapView source code is available under the GNU Affero General Public License, version 3, subject to the repository's license and attribution notices. Third-party components have their own licenses.
These website terms do not replace the software license or restrict rights it grants. A dataset license applies to dataset content; it is separate from the viewer's software license. COLMAP, Google Drive, and Hugging Face are independent projects or services; their mention does not imply endorsement.
8. Changes and contact
We may update these terms as the website changes. The effective date appears above. If you do not accept an update, stop using the website and disconnect any provider accounts as needed.
For support or questions about these terms, contact OpsiClear LLC at info@opsiclear.com. General development questions and public bug reports can be posted to the GitHub issue tracker.
