Privacy Policy
This Privacy Policy explains how Stellarcast Private Limited ("Stellarcast", "we", "us") collects, uses and protects information when you visit stellarcast.ai, interact with our forms, or use the Stellarcast app. We keep it short because we collect little.
Information we collect
We only collect what you choose to give us, plus privacy-preserving analytics:
- Free audit. The audit runs in the Stellarcast app, where we collect the domain you want measured, your email address and the market to measure in. (This page previously described a longer form that also asked for a name, company and phone number; that form was retired when the audit moved into the product.)
- Newsletter. If you subscribe from a blog post, we collect your email address and a note of which page you subscribed from.
- Analytics. We use two measurement tools on this site. Our own first-party engagement tracker is cookieless, records only aggregate page behaviour such as scroll depth and time on page, stores no personal data, and respects your browser's Do Not Track setting. The same tracker runs on the public pages of the Stellarcast app (pricing, free audit, sign-up and log-in), where it also records which buttons and links are clicked; it never records what you type into a form, and it does not run once you are signed in. Google Analytics 4 does set cookies (for example
_ga) and is provided by Google, which may use the data in line with its own policies; it tells us which pages and channels bring visitors here, and records when someone clicks a call-to-action or completes the audit or newsletter form, so we can see which pages and prompts actually lead somewhere. Together they give us aggregate figures like page views, referring sources and engagement. - Embedded video. Some blog posts include a product video hosted on YouTube. Nothing loads from YouTube until you press play: the page shows our own preview image instead. Once you press play, the video loads from YouTube's privacy-enhanced domain (youtube-nocookie.com), YouTube's own privacy policy applies to that playback, and Google Analytics records that the video was played.
We do not use advertising cookies, and we do not sell your personal information.
How we use it
- To run the audit you asked for and send you the report.
- To send you the occasional newsletter you subscribed to (you can unsubscribe at any time).
- To understand, in aggregate, how the site is used so we can improve it.
Google user data
This section is about Google accounts you choose to connect inside the Stellarcast app. It is separate from the Google Analytics we run on this website, which is described under Analytics above.
If you connect Google Analytics or Google Search Console in the app, you grant Stellarcast two read-only permissions. We use them for one purpose: to show you whether the changes you make to your website affect real visitors, not only whether AI assistants mention you.
What we read
- Google Analytics (
analytics.readonly). We list the Analytics properties your account administers, so you can choose which one matches the website you are measuring, and we store only the identifier and name of the one you pick. We then read aggregate report rows for it: counts of sessions and conversions grouped by channel and date. - Search Console (
webmasters.readonly). We list the sites you have verified so you can choose one, and read aggregate search performance rows for it.
What we never do
- We never write. Both permissions are read-only. We do not change your Analytics or Search Console settings, create or alter properties, submit sitemaps, or request indexing.
- We do not read individual visitors. We request aggregate rows only. We do not request or store user-level or event-level records, and we never receive the identity of anyone who visited your site.
- We touch no other Google service. No Gmail, Drive, Calendar or Contacts. The two permissions above are the only ones we ask for.
- We do not use your Google data to train AI models, ours or anyone else's, and we do not use it for advertising.
How to disconnect
Either works, and you can do it at any time:
- In the Stellarcast app, open Connections and disconnect Google. This erases the stored credentials.
- In your Google Account, open Third-party apps with account access and remove Stellarcast. Google invalidates our access immediately.
Revoking through Google does not remove figures we have already read. Use the in-app disconnect, or delete your account, if you want those gone too.
Limited Use
Stellarcast's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Where it is stored
Form submissions are stored in a database hosted on Cloudflare's infrastructure. We take reasonable measures to protect it. We retain your information for as long as needed to serve the purposes above, and we will delete it on request.
App data, including anything we read from a connected account, is stored on Google Cloud in Europe. Connection credentials are held in a dedicated secret store, never in our application database, which holds only an opaque reference to them. Credentials are erased when you disconnect or delete your account. Aggregate figures we have already read are kept for the life of your account, because a measurement of what changed after a fix is only useful if the earlier reading survives; deleting your account deletes them.
Sharing
We do not sell or rent your personal information. We share it only with the service providers below, and only as needed to deliver the service. We may disclose information if required by law.
Who we share it with, and why. These are our sub-processors. A buyer who needs this list under Article 28 of the GDPR has it here rather than on request.
- Google Cloud (europe-west1) - hosting, application database and file storage. Your account data and every measurement lives here.
- Cloudflare - this website and its form submissions.
- Paddle.com Market Ltd - payments. Paddle is the merchant of record and takes your billing details directly; we never see or store a card number.
- DataForSEO and Bright Data - the vendors that put your tracked questions to the AI engines on our behalf. They receive the prompt text and the market, not your account details.
- Google (Gemini) - drafting assistance during onboarding and remediation, on your brand and category. Remediation drafts are generated from your brand facts and either our summary of the gap being fixed or, for answer pages, the tracked question. Before sending, we remove email addresses and most phone number formats from the facts and drop fields named for a person or a contact detail (such as founder, team, email, phone or address). The gap summary and question text are sent as written. This drafting may be processed outside the EU under Google's Cloud Data Processing Addendum.
- Postmark - transactional email: verification, invitations, alerts and digests.
- Google Analytics - aggregate website usage on this marketing site.
- Razorpay - payments, for customers billed in India rather than through Paddle.
- xAI - only for enterprise customers whose contract includes Grok as a tracked engine. No self-serve plan reaches it.
If you connect an account of your own - Google Analytics, Search Console, Shopify, Cloudflare or a CMS - we read only what that connection's scopes allow, and the credential is held in a dedicated vault rather than in the application database.
Your choices
- Unsubscribe from the newsletter at any time using the link in any email, or by contacting us.
- Access or delete the information you have given us by emailing hello@stellarcast.ai.
- Disconnect Google, Slack or Shopify at any time from Connections in the app, which erases the stored credentials.
- Opt out of Google Analytics using Google's browser opt-out add-on, or by blocking cookies for this site in your browser. Our own first-party tracker remains cookieless, and it stops collecting entirely if your browser sends a Do Not Track signal. Google Analytics does not act on Do Not Track, so opting out of it needs the add-on or cookie blocking above rather than that browser setting.
Changes
We may update this policy as the product evolves. When we do, we will change the date at the top of this page.
