Your Privacy Choices
Choose your region and decide whether to allow available optional categories. Necessary service and security storage is explained in the Cookie Policy. Optional analytics and advertising vendors are not installed in this release.
Guest preferences stay on this device. When you are signed in, you can save the preferences to your own profile. The controls show the current choice, policy version and save status. A cookie preference does not change your research membership, access approval or preview-list subscription.
A copy of your saved privacy choices
Download my privacy choices exports only the confirmed saved privacy preference shown by these controls. It contains the current browser choice or the verified member’s saved privacy choice, as available. Unsaved edits are not exported. The download is a JSON file you choose to save.
This privacy-choice download is not a full account export or a complete legal access response. It does not export your account profile, access record, preview-list record, correspondence or provider logs. Email research@piphotonic.com to request a copy of your account data, a broader access response or an explanation of a record.
Request access, correction, deletion or an appeal
You can prepare a data request addressed to research@piphotonic.com. Describe whether you want access, a portable copy, a correction, deletion, a restriction, an objection or review of a prior decision. Include the account email and only the information needed to explain the request.
The request control opens a draft in your email application. You review and send it there; opening a draft does not submit a request. You can also write to the address directly if a mail application is unavailable.
Requests are reviewed manually. We may verify identity before disclosing or changing personal information and may retain records where the law permits or requires it. A deletion request does not instantly erase the account or provider backups. We will explain the result, any relevant exception and the response or appeal route required by applicable law.
Research Preview List updates
The preview list records a separate opt-in after email verification. To stop optional research updates, email research@piphotonic.com with a withdrawal request. Necessary sign-in or account messages remain separate.
Signing in, accepting available cookie categories or downloading a sample does not independently subscribe you to future marketing.
Local simulations and downloaded files
Numerical simulations run locally, and the application does not upload the run. You can clear site data to remove saved device preferences and sign-in state. Active page inputs are generally lost when the page is closed or refreshed.
A downloaded PDF, CSV or JSON file is controlled by you and your browser. Signing out does not remove a saved file. On a shared device, clear files or drafts you do not want another person to access.
Policies and help
The Privacy Policy describes information, purposes, providers, retention and regional rights. The Cookie Policy describes device storage. The Terms of Service describe account access and use of the research.
These pages take effect on October 7, 2026. Privacy choices are available without signing in, and asking about your data does not require an upgrade.
Your privacy choices
Necessary services stay on. Optional choices are yours.
No optional analytics or advertising tools are installed in this edition. These settings record your preference; they do not install tracking. Any future optional tools require updated disclosures and a fresh choice.
Exports the confirmed browser choice only. For account data access, correction, deletion, or Research Preview List withdrawal, email the research team. This link opens your email app; requests are reviewed manually.
