## Data

- Freshness: stored
- Keep data: While your account is in good standing, on termination you must delete results you hold within 30 days and any backup copies within 90 days
- Use data: Subject to these Terms and to your plan, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to use anvendor for your own internal business purposes for as long as your account is in good standing. Within that licence you may: Run searches and view results. Store results internally, and export your own search history in the formats we provide. Use results to inform your own sales, marketing, recruiting, partnership, procurement, competitive, or investment research. Quote individual data points in your own internal documents and in client-facing work, in limited quantity and incidental to your own analysis, with attribution to anvendor. The data is licensed to you, not sold. Everything not expressly permitted here is reserved. [...] You must not, and must not permit anyone else to: (a) Build, train, improve, or operate any product or service that competes with anvendor, or use anvendor to benchmark or evaluate for that purpose. (b) Systematically extract, accumulate, or retain results in order to reconstruct, approximate, or substitute for any material part of the anvendor dataset. (c) Use results to create, train, fine-tune, or evaluate any machine learning model, dataset, or automated analytics product that reproduces or substitutes for anvendor. Using results as an input to your own internal analysis is permitted, building a replacement for our service is not. (d) Resell, redistribute, sublicense, or otherwise make results available to anyone outside your organisation beyond what section 7 permits, including on freelance or marketplace platforms. (e) Publish results on any page or feed that is accessible without authentication, or otherwise make them publicly available. (f) Access the service other than through the interfaces we provide — the website, the anvendor API and its MCP server, use bots, crawlers, scrapers, or automation against the website (automated use belongs on the API, with your API keys), or circumvent rate limits, quotas, seat limits, metering, or any other technical control. (g) Reverse engineer, decompile, or attempt to derive our method, expressly including by inference from patterns across results, by probing the service with constructed queries designed to reveal how it works, or by any other indirect means. (h) Share credentials, or allow use of your account by anyone who is not an authorised user under section 4. (i) Copy or imitate anvendor's site structure, page templates, or search-engine-facing elements. (j) Use results for unlawful marketing or spam, for harassment, for discrimination, or to make a decision about an individual person — including any decision about their employment, credit, insurance, housing, or eligibility for a service. anvendor is not a consumer reporting agency and results must never be used as though it were one. (k) Use the service to harm, defraud, or misrepresent any third party, or present results as verified facts about a company. (l) Interfere with the security or integrity of the service, or probe it for vulnerabilities other than under a security disclosure we have agreed in writing.
