Privacy Policy

Effective Date: 8 August 2026

FTIR.fun provides online spectrum analysis tools and professional spectral interpretation services. We are committed to protecting your privacy, respecting intellectual property rights, and handling your data responsibly.

Information We Collect

We may collect personal information such as username, password, email address, profile details, and information submitted during service usage.

We may also collect non-personal information including browser type, usage data, pages visited, and general interaction data.

We may also collect and log your IP address and related technical metadata (such as browser and device information) where necessary for security, abuse prevention, and the operation of the service.

Images uploaded to the free image-to-spectrum extraction tool and the extracted curve/CSV data produced from them are used to improve its curve-detection model, but no personal identifiers (such as your username or IP address) are stored with that training data.

How We Use Your Information

We use collected information to provide and maintain our services, manage user accounts, and communicate important updates.

The standard analysis workflow follows the account route. Free users submit a public search: the spectrum is added to the community reference library and may be used for FTIR.fun model training. Paid users receive a private search by default: the spectrum is used only to deliver, store, and retrieve the result; it is not used for model training or library expansion and is not displayed to other users. Paid users may provide optional prior information, which is saved with the private task.

We take a narrow, purpose-limited approach to data use: any secondary use of data is described explicitly in this policy, tied to a concrete service benefit, and never extended beyond what is stated.

Analysis Feedback and Verification Data

When you voluntarily submit feedback or later verification about an analysis, the feedback record may be used to evaluate, correct, and improve AI/LLM-assisted judgment, prompts and rules, retrieval and decision logic, and evaluation methods.

Feedback is separate from the underlying raw spectrum. Submitting feedback does not change a private search into a public contribution and does not authorize that spectrum for model training or public-library use.

Discussing or sharing a result publicly outside the public help discussion area does not, by itself, authorize model training or library contribution. Content separately posted in the public help discussion area is handled under its stated public permission below.

Cookies

FTIR.fun uses essential session cookies and CSRF tokens required for secure authentication and service operation. These cookies are strictly necessary.

The site does not currently load separate analytics or advertising cookies.

Advertising and Google AdSense

FTIR.fun may use Google AdSense in the future. Advertising is not currently enabled, and the AdSense account verification tag does not display ads or set advertising cookies.

If advertising is enabled, third-party vendors, including Google, may use cookies, local storage, or device identifiers to serve and measure ads. Where required by law, personalized advertising will be used only after the necessary consent has been obtained. You can learn how Google uses information from sites that use its services in Google's Privacy & Terms guidance and manage ad personalization in Google Ads Settings.

Third-Party Processors

We engage the following categories of third-party service providers to operate the service: cloud infrastructure and CDN providers (including Cloudflare), payment processors (including PayPro Global), hosting providers, and AI/LLM providers. These processors are contractually bound to handle data only per our instructions and applicable data protection laws.

When you request an AI-assisted analysis (spectral interpretation, material identification, peak assignment, or support chat), the spectrum data and sample information you provide for that analysis are sent to third-party AI model providers to generate the result. This is required to deliver the service you requested. The AI providers may process this content on servers located in different countries. We do not license your content to these providers for model training, and your content is not used by them to train their models unless the provider states otherwise under its own data terms.

Reference Data and Literature Enhancement

FTIR.fun improves peak-assignment accuracy by consulting public scholarly indexing metadata (such as bibliographic records and abstracts made openly available by academic indexing services and open-access publishers under their own terms). This metadata is factual bibliographic information, not copies of protected works.

Use of such public metadata is limited to: (1) identifying whether a published study reports the infrared peak position you are investigating, and (2) improving the interpretation we provide to you. Reports contain only objective spectral values and, where helpful, a minimal citation (source, authors, publication, and a short reference sentence) — never full-text reproduction, never wholesale copying of any work, and never redistribution of any third-party database.

We do not claim ownership of any third-party scientific work referenced in our reports, and we do not make full texts or protected figures available to users.

Data Storage and Cross-Border Transfer

User data is stored on servers located in the jurisdictions where our hosting infrastructure operates. For users outside these jurisdictions, data may be transferred across borders as necessary to provide the service. We implement appropriate safeguards to ensure data protection during such transfers in accordance with applicable law.

For transfers of personal data out of the EEA/UK, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses (or equivalent mechanisms). You may request information about these safeguards at ftir.fun@outlook.com.

Data Retention

We retain personal data only for as long as necessary to fulfill the purposes for which it was collected, or as required by applicable law. Users may request early deletion of their data by contacting us. Institutional and enterprise data under zero-retention plans is permanently deleted after report delivery as specified in the applicable agreement.

Your Rights

Depending on your jurisdiction, you may have the following rights regarding your personal data: access (request a copy of data we hold about you), rectification (correct inaccurate data), erasure (request deletion of your data under certain conditions), restriction of processing, data portability, and the right to object to processing. To exercise any of these rights, please contact us at ftir.fun@outlook.com. We will respond within the timeframe required by applicable law.

If you are in the EEA or UK, you also have the right to lodge a complaint with your local data protection supervisory authority.

Children's Privacy

FTIR.fun is not intended for use by individuals under the age of 16. We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us so we can promptly remove it.

Automated Decision-Making

FTIR.fun provides AI-assisted spectral interpretation as a research and analysis aid. AI-generated outputs are not binding decisions and should always be independently reviewed by qualified professionals. Users are not subject to automated decisions that produce legal effects or similarly significant consequences without human review.

Information Sharing

We do not sell personal data to third parties. Information may be shared when required by law or when necessary to operate the service, such as payment processing or hosting.

Public Data and AI Usage

When a free user submits a standard public search, the submitted spectrum becomes a community reference-library record and may be used for FTIR.fun model training. Search results may identify the contribution by spectrum number, show the submitted metadata in its original language, and provide a private-message route to the contributor through FTIR.fun.

A spectrum's content may be used for a free public search only once; changing its filename does not create new eligibility. The same IP address may submit one free public search every 5 minutes. Truthful sample background information is mandatory. If the material name, composition, or preparation method is unknown, you may say so, but you must describe the known source or context, such as a foreign object, student experiment, or where the sample was obtained. Empty, meaningless, or clearly fabricated information is rejected and the IP address is blocked.

Public Help Discussion is a separate data-use path. Content you post there, including spectra, images, notes, sample context, and discussion text, is visible to others and will be used for FTIR.fun reference-library retrieval and model training.

Before posting, make sure you have the legal right to share the content. Do not upload confidential, trade-secret protected, subject to non-disclosure agreements (NDA) with third parties, or otherwise legally restricted data unless you have prior written authorization from the rights holder.

Online Requirement submissions are a separate service-delivery path. Spectra, images, supporting files, sample context, and related information submitted through Online Requirement are handled by the FTIR.fun technical team to deliver the requested service. They are not used as reference-library records for retrieval or model training.

A private standard analysis remains separate from public contribution and public discussion. Its spectrum is not used for model training or library expansion and is not displayed to other users.

The image-to-spectrum extraction tool is another separate path: spectrum images and the extracted curve/CSV data from that tool are used to improve the curve-detection model, but they are not used as reference-library records for retrieval.

Public contributions, private analyses, public discussion data, and image-to-spectrum uploads have different purposes and should not be treated as interchangeable.

Find Spectrum

Find Spectrum is free. For standard users, the privacy-limited response contains the spectrum number, whether a match was found, and only a partial spectrum window (1000–1400 cm⁻¹) of the top match; material names, CAS numbers, structures, synonyms, the complete curve, and AI-generated candidates are not returned. Accounts with full access may receive the complete reference metadata.

Image-to-Spectrum Extraction Tool

The image-to-spectrum extraction tool is a free utility that converts a spectrum image into a numerical curve. To keep this free tool working well, spectrum images uploaded through this specific tool are used to improve the automatic curve-detection model that powers it. This is clearly disclosed on the tool page before you upload.

The image-to-spectrum tool uses the uploaded image and extracted curve/CSV data for curve-detection model training only. It does not make them reference-library records for retrieval; personal identifiers such as your username are not used to label or evaluate the training data.

If you prefer not to have your image or extracted curve/CSV data used for curve-recognition training, use a private raw-file analysis instead. A public raw-file search has the separate public-library and model-training permission described above.

Security

We implement reasonable technical and organizational measures to protect user data, including secure servers and encrypted storage where appropriate.

Policy Updates

We may update this Privacy Policy from time to time. Material changes will be announced on our website or via email.
