Cadrelle is operated by Sfumato Studios LLC.
When this policy says “Cadrelle,” “Sfumato Studios,” “we,” “us,” or “our,” it means Sfumato Studios LLC.
When you visit cadrelle.art, we use a small number of services to operate the website, understand aggregate traffic, and let visitors join the launch list.
The “Notify me” form asks for one thing: your email address.
Your email address is transmitted to Formspark, our form processor, which processes the submission on our behalf. Formspark may also receive ordinary technical data needed to process the form submission, such as IP address, browser type, device information, timestamp, and referring page.
We use your email address only to send Cadrelle launch-related communication unless you separately choose to receive more from us.
After the launch announcement or launch-related communication is complete, we intend to delete launch-list emails from our active systems unless you have separately opted in to future communication.
We use Vercel Web Analytics to understand site traffic in aggregate.
Vercel Web Analytics helps us see information such as page views, top pages, referring sites, countries, and general usage patterns. We do not use it to create advertising profiles, identify individual visitors, or follow visitors across unrelated websites.
Vercel Web Analytics is designed without third-party cookies and provides privacy-preserving aggregate analytics. Like most web infrastructure services, Vercel may process technical request data needed to deliver and secure the website.
Cadrelle may load fonts, images, scripts, and other site assets needed to display the website. Where practical, we prefer to self-host assets to reduce unnecessary third-party requests.
If we use externally hosted fonts or assets, the provider may receive ordinary technical request data, such as your IP address, browser information, and the page requesting the asset.
Cadrelle is designed to be offline-first and privacy-forward.
Core activity in the app — including paintings restored, notes read, quizzes completed, distinctions earned, and progress through the collection — is designed to stay on your device unless we clearly say otherwise.
This means:
We do not use your app activity to build advertising profiles. We do not know which paintings you personally restore, which notes you personally read, or how long you personally spend with a specific artwork unless the app is later changed to include a feature that clearly requires this and this policy is updated.
Cadrelle may store app progress, preferences, completed puzzles, distinctions, and similar app data locally on your device.
If you delete the app, change devices, erase your device, or lose your device, locally stored app data may be lost unless your operating system or device backup settings preserve it.
Apple, Google, and your operating system may provide crash reports, diagnostics, install information, device information, or similar platform-level data under their own privacy policies and device settings.
Those platform channels are separate from Cadrelle. We may receive aggregated or developer-facing diagnostic information from Apple or Google, but we do not use it to track your behavior across apps or websites.
Cadrelle memberships and in-app purchases are handled through the Apple App Store or Google Play, depending on where you purchase.
We do not receive your full card number, payment credentials, billing address, or bank information.
Depending on the platform, purchase flow, and technical implementation, we may receive or process purchase-related records needed to provide access, restore purchases, prevent fraud, comply with law, or support your membership. These records may include:
If you need to manage, cancel, or request a refund for a subscription purchased through Apple or Google, you must do so through the applicable platform.
Cadrelle is intended for a general audience interested in art, visual culture, and educational play. It is not directed to children under 13.
We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, contact us at hello@cadrelle.art and we will take appropriate steps to delete it.
If a future version of Cadrelle is directed to children or includes child-specific features, we will update this policy and our platform disclosures before launch.
We use the limited information we collect for the following purposes:
We do not use personal information for third-party behavioral advertising.
We may use service providers to operate Cadrelle. These providers process information on our behalf or provide platform services.
Current or expected providers may include:
We may replace, remove, or add providers as Cadrelle evolves. If we add a provider that materially changes how personal information is collected or used, we will update this policy.
We keep information only as long as reasonably necessary for the purpose for which it was collected.
Launch-list emails are intended to be kept only for launch-related communication unless you separately opt in to future communication.
Purchase and subscription records may be kept as long as needed to provide access, restore purchases, maintain business records, resolve disputes, prevent fraud, comply with platform rules, or meet legal obligations.
Support, legal, or privacy-request emails may be kept as long as reasonably necessary to respond, maintain records of the request, and comply with law.
Aggregate analytics may be kept in non-identifying form.
Depending on where you live, you may have rights under privacy laws such as the GDPR, UK GDPR, California privacy law, and other applicable laws.
These rights may include the right to:
Because Cadrelle is designed to collect very little personal information, there may be limited information for us to provide or delete.
To make a privacy request, write to:
We will respond within 30 days unless applicable law allows or requires a different period.
We do not sell personal information.
We do not share personal information for cross-context behavioral advertising as those terms are commonly used under California privacy law.
We do not knowingly sell or share the personal information of children under 16.
We do not use sensitive personal information to infer characteristics about you.
If California privacy law applies to your request, you may have the right to know, access, correct, delete, and limit certain uses of personal information, and the right not to be discriminated against for exercising privacy rights.
Cadrelle is operated from the United States.
If you access Cadrelle from outside the United States, your information may be processed in the United States or in other countries where our service providers operate. These countries may have privacy laws that differ from those in your country.
Where required, we rely on appropriate legal bases for processing personal information, including consent, contract necessity, legitimate interests, legal obligations, and the operation of requested services.
We use reasonable administrative, technical, and organizational measures to protect the limited information we process.
No website, app, platform, or transmission method is completely secure. We cannot guarantee absolute security, but we design Cadrelle to reduce risk by collecting as little personal information as reasonably possible.
We may update this Privacy Policy from time to time.
If we make a material change, such as adding a new category of personal information collected by Cadrelle or introducing behavioral analytics, cloud accounts, or advertising tracking, we will update this page and, where appropriate, provide additional notice.
The “Last updated” date shows when this policy was last revised.
