Serial Number Decoder

Professional Serial Number Age Decoder for Appliances & Equipment

🔒 Privacy Policy

How we handle data collected through our tools. Last updated: February 27, 2026.

Item Assist (“we,” “us,” or “our”) operates this website at decodemyitem.com. This Privacy Policy explains what data we collect, how it is processed, which third-party services receive it, and your rights regarding that data. By using Item Assist you agree to the practices described here.

1. Data We Collect

a) Search Inputs

When you use the Serial Number Decoder, the serial number and brand you select are processed entirely within your browser. No serial number is transmitted to our servers during a successful rule-based decode. If the decoder cannot produce a result, a brief alert is sent to our internal monitoring system containing the brand name, serial number entered, product category, and a failure reason. This is used solely to improve decode accuracy.

When you use Smart Lookup, the free-text query you submit (maximum 200 characters) is sent to our server and forwarded to an external AI inference service to generate a response. See the Security & Data Protection tab for full details on how AI providers handle this data.

b) Contact and Feedback Forms

If you use our contact form or submit a decoder error report, we collect the information you voluntarily provide: your name (optional), email address (optional), and your message or feedback. This information is delivered to us via email and is not stored in any application database.

c) Automatically Collected Technical Data

Our hosting provider (Vercel) automatically collects standard technical data when you visit the site, including:

  • IP address (used for rate limiting; not linked to your identity)
  • Browser type, version, and operating system
  • Device type and referring URL
  • Timestamps of page requests

d) Cookies

  • Functional cookies: Small values stored in your browser (e.g., your last-selected product category) to improve your experience. These are not shared with third parties.

2. How We Use Your Data

  • To operate the Serial Number Decoder and Smart Lookup tools
  • To cache AI responses for up to 14 days to improve response speed and reduce redundant AI queries
  • To enforce rate limits and prevent automated abuse (using your IP address, which is not stored beyond the active rate-limit window)
  • To respond to contact form and feedback submissions

We do not sell your personal data to third parties. We do not build individual user profiles. We do not use your data for any purpose beyond those listed above.

3. Third-Party Services

Item Assist relies on the following third-party services. Each service receives only the minimum data necessary for its function.

AI Inference Providers (Smart Lookup only)

When you submit a Smart Lookup query, your query text is forwarded to one of the following AI providers:

Provider Role Trains on your data? Data sent
Google Gemini API
generativelanguage.googleapis.com
Primary AI provider NO
Paid API tier — Google’s Terms explicitly prohibit use of API prompts or responses to train or improve their models.
Your query string only. No IP address or identifying information is included.
Groq API (Llama 3.1)
api.groq.com
Fallback AI provider (used only if Gemini is unavailable) NO
Groq’s Services Agreement explicitly prohibits use of customer inputs or outputs for model training.
Your query string only. Same data as Gemini.
🔒 AI Data Commitment

Neither AI provider we use will train on your queries. Google’s commitment applies specifically to paid-tier Gemini API usage (which this service uses). Groq’s prohibition is written into their Services Agreement for all customers. Your searches are used solely to generate a response and are not retained by either provider beyond operational logging windows.

Infrastructure Services

Brand + serial (decode alert deduplication key) Upstash Redis 24 hours, then automatically deleted
IP address (rate-limit state) Upstash Redis Active rate-limit window only (minutes), then automatically deleted
Contact form and feedback submissions Resend email logs 1–7 days depending on Resend plan, then delivered to our inbox and purged
Serverless function error logs Vercel 1 hour–3 days depending on plan; logs do not contain user query content under normal operation
Gemini API optional developer logs Google (opt-in only) 55 days if developer logging is enabled; not enabled by default
Groq API data Groq None by default. Up to 30 days only for reliability or abuse investigation.

5. Your Choices

Cookies

You can manage or delete cookies through your browser settings. Disabling cookies will not affect the Serial Decoder or Smart Lookup functionality.

Do Not Track

Because this site does not use behavioral analytics or user tracking, Do Not Track signals have no additional effect on our data practices beyond what is described in this policy.

6. Children’s Privacy

Item Assist is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has submitted personal information, please contact us so we can remove it promptly.

7. Changes to This Policy

We may update this Privacy Policy from time to time as our services or applicable law changes. Updates will be posted on this page with a revised effective date. Continued use of Item Assist after a change constitutes acceptance of the revised policy.

8. Contact

This section summarizes the technical and organizational measures in place to protect your data. It is intended for users, employers, and IT departments evaluating this service.

Encryption and Transmission Security

All connections to decodemyitem.com are encrypted using HTTPS. A Strict-Transport-Security (HSTS) header with a one-year maximum age, subdomain coverage, and preload status is enforced on every route. Data in transit to all third-party services (Gemini, Groq, Upstash, Resend) is also encrypted using TLS.

Infrastructure Security Certifications

Service SOC 2 Type II ISO 27001 GDPR Other
Vercel YES YES (2022) YES
Upstash Redis YES In progress YES HIPAA compliant
Resend YES YES AES-256 at rest; TLS 1.3 in transit
Google (Gemini / Fonts) YES YES YES ISO 27017, ISO 27018
Groq Not published YES (DPA available) Data stored on Google Cloud US

No Account or PII Required

Item Assist does not require user registration, login, or any form of identity verification. No account credentials, payment information, health data, or government-issued identifiers are ever collected. Serial numbers and model numbers are not inherently personally identifiable information, though users should avoid submitting data they consider sensitive.

Secrets and Credential Management

All API keys and service credentials are stored exclusively as encrypted environment variables in Vercel’s infrastructure. No credentials are hardcoded in any source file or committed to version control. The project’s git history has been audited and confirmed free of exposed credentials or personal identifiers as of February 27, 2026.

Content Security Policy

A strict Content Security Policy (CSP) header is active on all pages. It explicitly allowlists only the domains required for the site to function (Google Fonts) and blocks all other third-party scripts, frames, and connections by default. This reduces the risk of cross-site scripting (XSS) and unauthorized third-party data collection.

AI Model Training Commitment

This service uses the paid tier of the Google Gemini API. Under Google’s API Terms of Service, paid-tier customers’ prompts and responses are not used to train or improve Google’s models. The Groq API is bound by the same restriction under its Services Agreement. Neither AI provider will incorporate your queries into model training.

Minimum Data Principle

Each external service receives only the minimum data required for its specific function. AI providers receive only the query string — no IP address, user-agent, or session data is included in AI requests. Cached responses are stored by query text only, with no linkage to the originating user or session.
