Overview
HueNest is designed to provide a calm color-by-number experience without accounts, advertising, cross-app tracking, or third-party behavioral analytics. This policy explains the limited information HueNest processes to deliver artwork, save anonymous progress, keep the service secure, and respond to support requests.
Information we process
Anonymous installation and progress data
HueNest does not require an account and does not ask for your name. When the app first connects, the service creates a random installation identifier and credential. The credential is stored on your device; the service stores only a protected digest used to validate future progress requests.
To back up progress for that installation, HueNest may process the artwork identifier and resource version, the order of filled regions, the selected color number, filled and total region counts, completion status, revision number, and necessary timestamps. This information is not connected to an account, Apple ID, advertising identifier, or cross-device profile.
Network, security, and diagnostic data
Our infrastructure may process standard request information such as IP address, request time, route, response status, request identifier, rate-limit events, and error details. We use this information only to deliver the service, prevent abuse, investigate failures, and maintain reliability. Apple may also provide crash or performance information according to your device analytics settings.
Support communications
If you contact support, we process the email address, message, and any diagnostic details you choose to provide so that we can respond.
Information that stays on your device
App settings, cached catalog data, downloaded artwork, progress previews, and completed images are stored locally. HueNest does not upload progress screenshots or completed images. When you tap Save, the app requests permission only to add the finished image to Photos; it does not read your photo library.
How we use information
- Provide the artwork catalog and secure artwork downloads.
- Save and update progress for the current anonymous installation.
- Operate rate limits, security controls, and service diagnostics.
- Respond to support requests you initiate.
Sharing and service providers
We do not sell personal information and do not use information for advertising or tracking across other companies’ apps or websites. We share only the information necessary for infrastructure providers to perform hosting, content delivery, database, object storage, security, and diagnostic services on our behalf. Cloudflare is used for website and service infrastructure. These providers process data under their own security and privacy obligations.
We may disclose information if required by law or when reasonably necessary to protect users, the service, or the public.
Retention and deletion
Active anonymous progress is retained while needed to provide the progress-backup feature. Replacing or restarting progress creates a newer revision. When you use Delete in the app, HueNest removes the local progress and derived preview images and replaces the active remote progress with a deletion marker so that older progress does not reappear. Downloaded artwork files remain on the device.
Deletion markers, security records, and rolling backups may be kept for a limited period when needed for data consistency, fraud and abuse prevention, legal obligations, or disaster recovery, and are removed or overwritten when no longer needed for those purposes. Uninstalling HueNest removes local app data but does not itself send a server-side deletion request. HueNest does not currently provide account-based, cross-device, or reinstall recovery.
Security
We use transport encryption, access controls, limited service credentials, and other reasonable safeguards appropriate to the information processed. No method of transmission or storage can be guaranteed to be completely secure.
International processing
Infrastructure providers may process information in countries or regions other than where you live. Where required, we use appropriate safeguards for those transfers.
Children’s privacy
HueNest does not knowingly ask children to provide names, account profiles, or contact details. If you believe a child has provided personal information through a support request, contact us so we can review and address it.
Changes to this policy
We may update this policy as the app or its service providers change. The updated policy will be posted here with a revised date.
