Privacy policy

Our tools

The Dry Eye Profile, Blink Test, Eye Break Timer and Drop Decoder run entirely in your browser. Your answers, camera feed and settings are processed on your device and are not sent to us, unless you choose to email yourself your Dry Eye Profile plan (see below).

Camera. The Blink Test asks for camera access only when you start it. Video is analyzed frame by frame in your browser and immediately discarded. Nothing is recorded, stored or uploaded, and the camera is switched off when the test ends.

Saved on your device. Some tools save small pieces of information in your browser’s local storage, such as your last profile score, timer settings and your light or dark mode choice, so they’re there next time. This data stays on your device. You can clear it at any time by clearing your browser’s site data.

What we collect

We only receive personal information when you send it to us through a form:

• Newsletter: your email address.
• Emailing your Dry Eye Profile plan: your email address and, while the email is being written, your profile type, symptom score and a coded version of your answers, which becomes the link that reopens your results. We use those only to create that one email and don’t keep them. We keep only your email address and whether you asked for the newsletter. Anyone with that link can open your results, so forward it only to people you’d share them with. Your answers sit after the # in the link, a part browsers never send to our server or our analytics.
• Clinic listing requests: if you work at a practice and ask us to claim, correct, add or remove a listing, the details you enter, such as your name, role, work email and phone number.
• Emails: whatever you choose to include.

An earlier version of this site had a specialist request form, which asked about your dry eye situation. It has been retired. If you sent one, we use it only to reply to you, and we’ll delete it if you ask.

We also receive the page you submitted a form from and your approximate country, to help prevent spam and understand demand.

How we use it

We use your information only for the purpose you gave it: to send the newsletter, to email your plan, to handle a practice’s listing request, or to reply to you. We don’t sell or rent your information to advertisers, data brokers or anyone else, and we don’t pass anyone’s details to a clinic.

Clinic directory. Searching the directory by ZIP code or city happens in your browser. We don’t receive or store what you type. When you call a practice or visit its website, you deal with that practice directly, and its own privacy policy applies. The directory shows business information that practices publish on their own websites.

Health information

Our forms don’t ask for health information. The Dry Eye Profile runs on your device, and its answers only reach us if you ask us to email your plan, as described above. We never use health information for advertising. Symvana doesn’t use advertising pixels or tracking tags from social media or ad networks.

Service providers

Symvana is hosted on Cloudflare, which processes technical data such as IP addresses to deliver and protect the site. Form submissions are stored securely with Cloudflare. We use an email service provider to send emails and a newsletter service to manage subscriptions. These providers only process data on our behalf.

Analytics. We use Cloudflare Web Analytics, which counts visits without cookies and without tracking you across other sites.

Affiliate links. When you follow a product link to a retailer such as Amazon, that retailer’s own privacy policy and cookies apply on their site.

Cookies

Symvana itself doesn’t set advertising or tracking cookies. Our hosting provider may set strictly necessary cookies for security.

Your choices and rights

You can unsubscribe from emails at any time using the link in each email. To see, correct or delete the information you’ve sent us, email hello@symvana.com and we’ll respond within 30 days. Depending on where you live, you may have additional rights under laws such as the GDPR or state privacy laws in the US, and we’ll honor them.

How long we keep it

We keep newsletter subscriptions until you unsubscribe, and listing requests, earlier specialist requests and other messages for as long as needed to handle them, up to two years, unless you ask us to delete them sooner.

Children

Symvana is intended for adults. We don’t knowingly collect personal information from children under 13.

Changes

If we change this policy, we’ll update the date at the top. Significant changes will be highlighted on this page.
