Terms of Service

Last updated: September 7, 2026

These Terms govern your use of Stacksift, a domain product analysis API

("we", "us", "Stacksift").

By creating an account, generating an API key, or using the Service, you

agree to these Terms. If you don't agree, don't use the Service.

1. The Service

Stacksift analyzes public B2B websites to identify the products a company

sells. Each call to our /v1/analyze endpoint returns a structured list of

products with supporting evidence URLs.

The Service is provided as-is. We use third-party search and language-model

providers (currently OpenAI and Serper) to produce results; their accuracy

and availability are outside our control.

2. Your account

You must provide a valid email and verify it before using paid features.

You're responsible for keeping your API keys confidential. API keys are

shown to you ONCE at creation; we never store them in plain text and cannot

recover them for you.

You may not share your account credentials with third parties or resell

access to the Service without a written agreement with us.

3. Acceptable use

You may not use Stacksift to:

  • Scrape, harvest, or compile personally identifiable information about

individuals

  • Send abusive traffic that interferes with the Service for other customers
  • Reverse-engineer, decompile, or attempt to extract our source code
  • Use results to enable surveillance, harassment, or other illegal activity
  • Circumvent rate limits or analysis consumption (one call = one analysis)

We reserve the right to suspend or terminate accounts that violate these

restrictions, retaining unused analyses as a service fee. Egregious cases

(fraud, abuse, illegal activity) result in immediate termination without

refund.

4. Analyses and payment

The Service operates on prepaid analysis packs. You purchase packs

in advance. Each call to /v1/analyze consumes one analysis, including

a repeat of the same domain. Failed calls are not charged.

All prices on stacksift.in are in US dollars (USD). Checkout is

handled by Dodo Payments, which is the merchant of record and calculates

tax for your billing country.

Analysis packs expire 180 days after purchase. We never see or store your

card details.

See our Refund Policy and Cancellation Policy

for details on returns and account closure.

5. Service availability

We target 99% monthly availability on a best-effort basis. We do not

currently provide an SLA with analyses or refunds for downtime. If you

experience a service issue, contact us and we may issue replacement analyses

at our discretion.

We may schedule maintenance with reasonable notice. We may also experience

unplanned outages caused by our upstream providers (OpenAI, Serper, Render).

6. Data and privacy

We analyze publicly-available web content on your behalf. We do not sell

or share customer data with advertisers or data brokers. See our

Privacy Policy for full details.

API call logs are retained for 90 days for billing and abuse-prevention

purposes. Each analysis call runs the live pipeline; we do not return a

prior result to skip that work. You can request export or deletion of your

account data by emailing us.

7. Intellectual property

You retain all rights to data you submit and to analyses produced for your

account. We retain rights to our pipeline code, prompts, training methods,

and aggregate non-identifying statistics across our customer base.

The Stacksift name, brand, and software remain our property. You receive a

non-exclusive, non-transferable license to use the Service per these Terms.

8. Liability

To the maximum extent permitted by law, our total liability to you for any

claim arising from your use of the Service is limited to the amount you

have paid us in the three months preceding the claim.

We are not liable for indirect, incidental, consequential, or special

damages, including lost profits, lost data, or business interruption.

9. Changes to these Terms

We may update these Terms. Material changes (pricing, scope of service,

liability) take effect 30 days after we email registered customers. Minor

changes (typos, clarifications) take effect immediately.

Continuing to use the Service after a Terms update constitutes acceptance.

10. Governing law

These Terms are governed by the laws of India. Courts at Bengaluru, Karnataka, have exclusive jurisdiction.

For international customers: this clause does not waive your rights under

your local consumer-protection law where it applies and cannot be

contractually limited.
