Plain language.
No tracking behind the scenes.

Saha is in active development. The only thing this site does today is collect an email address so we can tell you when early access opens. There is no app yet, no voice check-ins yet, no health data yet.

That means our privacy surface area is tiny — and we're writing this page to lock in the commitments now, before the product gets bigger.

• Your email addressSo we can email you when early access opens. That's the entire reason.
• The timestamp of when you signed upSo we can roll out access in waves and prevent duplicate signups.

That's it. We don't ask for your name, your condition, your location, your phone number, or anything else. If a field isn't on the form, we don't have it.

• No tracking pixelsWe don't run Google Analytics, Meta pixels, TikTok pixels, LinkedIn Insight, Hotjar, FullStory, or session replay. Inspect the page source — there are no third-party trackers loaded.
• No advertising networksSaha is not ad-supported. We don't share data with ad networks because we don't have a relationship with any.
• No selling, everWe will not sell your email or any future health data to anyone. Not to data brokers, not to insurers, not to pharma. This isn't going to change.
• No AI training on your transcriptsWhen the product launches and you start speaking to Saha, your voice transcripts will not be used to train language models — ours or anyone else's. Your speech belongs to you.

We're writing this so you know what's coming. When Saha opens to early access, the app will need a few categories of data to do its job:

• Voice check-insAudio you record (or its transcription) is stored so you can scroll back through your timeline. You can delete any check-in. You can delete all of them.
• Health data you enterMedications, doctor visits, blood work, symptoms, mood. Anything you tell Saha about your health. Stored to power patterns and reports.
• Account basicsEmail, optional name, condition selection, time zone.

We'll publish a more detailed version of this section before anyone starts using the app. Nothing on this list is being collected today.

Right now, the only people with access to the waitlist are the small team building Saha. We use your email to send you one or two messages: a confirmation, and a notification when early access opens. We don't add you to a marketing list. We don't share it with partners.

When the product launches, your health data will be visible to you and to people you explicitly choose to share it with (e.g. a doctor receiving your generated report). Nobody else.

We try to use the smallest stack possible. Today the page is served by our hosting provider, and the waitlist email is stored in Convex, our backend database. Convex stores data encrypted at rest. When we add an email-sending service, we'll name it here.

We'll keep this section honest as the stack grows. If we add a service that processes your data, you'll see it on this page.

• Ask what we haveEmail us and we'll tell you exactly what's stored against your address.
• Get it deletedEmail us and we'll remove your address from the waitlist. We aim to do it within a week.
• Export itRight now there's nothing to export but an email. When the product launches, you'll be able to export your full record from inside the app.

For any of these, email prakash.rewant24@gmail.com and we'll handle it.

We don't set tracking cookies on this site. Your browser may store small technical items (like the waitlist form remembering your email if you fill it in twice in a row) but nothing is shipped to a third party for analytics or advertising.

Saha is not designed for children under 13 and we don't knowingly collect data from them. If you believe a child has joined the waitlist, email us and we'll remove their entry.

When we update this page, we'll change the “last updated” date at the top and note what changed in plain language. If a change materially affects how your data is used, we'll email you about it.

Saha is being built as a companion for people living with autoimmune conditions. It will not be a substitute for medical care, diagnosis, or treatment. Talk to your doctor about any health decisions.
