Privacy policy
Heartbeat is a product of SISU Data. Last updated November 9, 2026.
What we collect
Your account: your email address and your password. Your password is handled by our sign-in provider and stored only in scrambled (hashed) form. We cannot read it.
Your profile: everything you type into Heartbeat. That can include your name, contact details, work history, education, certifications, awards, skills, achievements, volunteer work, interests, and any saved versions of that information. You decide what goes in.
Your trial code: which access code you used and when, so each code works once.
What we do with it
We use it to run your account: sign you in, show your profile back to you, keep your saved versions, and create your Word export when you ask for one. We do not sell your information. We do not show ads. We do not use your profile to train AI models.
Heartbeat does not currently run any AI review or job matching on your profile. Resume upload, AI review, and job matching are planned features. Before we turn on any feature that sends your profile to another service, we will update this policy and tell you.
Who holds your data
We use two outside services to run Heartbeat. Supabase stores your account and profile in its database. Vercel hosts the website and generates your Word export. Both process your data only to provide those services.
Your profile is protected by access rules in the database so that signed-in users can only reach their own rows. SISU Data staff with administrator access to the database could technically see stored data, and we will only look at it to run, fix, or secure the service, or if the law requires it.
Cookies and tracking
Heartbeat does not use advertising or analytics trackers. Your browser stores a sign-in session so you stay logged in. That is all the site needs. The main SISU Data website, sisu-data.com, is separate and uses Google Analytics.
Keeping and deleting your data
Your data stays in your account until you ask us to remove it. To delete your account and everything in it, email the address below and we will do it within 30 days. You can also edit or delete your saved versions yourself at any time inside Heartbeat.
Your choices
You can ask to see, correct, export, or delete your information. Your Word export is available to you at any time inside Heartbeat. For anything else, contact us.
Changes
If we change this policy in a way that matters, we will update the date above and let account holders know.
