Last updated August 17, 2026. This page covers what data we collect, where it goes, how long we keep it, and the terms of the service. It is written to be read, not to be impenetrable.
We use your property address to look up public assessment and sales records, estimate whether your home is assessed above its market value, and if it is, prepare your county's own review form. You review and sign it. We then deliver it to your County Assessor.
We do not sell your data. We do not share it with data brokers. The only party we hand your filing to is the County Assessor you asked us to file with.
When you check a property (free): the address you enter, and the public records we retrieve for it, including the parcel number, assessed value, building characteristics and nearby comparable sales. If you give us an email address to save your result, we store that too.
When you file: your name, phone number, email address, mailing address, your opinion of value, and the comparable sales chosen for your filing. Every one of these appears on the county form itself, because the county asks for them.
Automatically: your IP address for rate limiting and abuse prevention, and how you arrived at the site (for example a search engine, an ad, or a link) so we know which channels bring people who find this useful.
Payment details are never collected by us. Card entry is handled inside our payment service's own hosted form. Card numbers do not reach our servers and we never store them. We see only that a payment succeeded, its amount, and the email you gave for the receipt.
Your County Assessor. This is the point of the service. Your completed, signed form and its comparable-sales worksheet go to the assessor's office, by mail, email or fax depending on what that county accepts. Once filed, that document is in the county's hands and subject to its own records rules, not ours.
Service providers who work on our behalf. We use third-party services for hosting, data storage, property and address data, e-signature, payment processing, email, print and mail, and messaging. Each receives only what it needs to do its job, and none is permitted to use your information for its own purposes.
Nobody else. We do not sell, rent, or trade your personal information. We do not share it with data brokers, lead buyers, lenders, agents, or marketers.
Filings: two years. A filed request is a record of something submitted on your behalf to a government office, so we keep it long enough to answer questions about it, prove what was sent, and support you if the county responds late or disputes receipt.
Free checks that never became a filing: about a year, so you can come back and pick up where you left off, and so we can improve the accuracy of the estimate.
Analytics and operational logs: shorter, generally thirty days to a year depending on the record.
You can ask us to delete your information sooner. See below.
The site uses standard analytics and advertising measurement tools so we can tell which channels bring people who find this useful, and so we do not pay to advertise to people twice. These use cookies and similar identifiers. They tell us that a visit or a payment happened; they are not given your filing contents.
You can block them with your browser's tracking protection or an ad blocker, and the site will still work normally.
Access, correction and deletion. Email support@saveproptax.com and we will tell you what we hold about you, correct it, or delete it. California residents have these rights under the CCPA, and we extend them to everyone. We will not charge you or treat you differently for exercising them.
One limit worth stating plainly. Once a filing has gone to the County Assessor we cannot retract it from the county's records, and we may need to retain our own copy of what was sent. Deleting your account does not undo a submitted filing.
Email. Every non-essential email has an unsubscribe link. Messages about a filing you actually made are transactional and will still reach you.
What this service is. We prepare a decline-in-value review request from public records and your county's own form. You review it and sign it. We deliver it. That is the whole service.
What it is not. We are not a law firm, an accountancy, or a licensed tax agent, and nothing here is legal or tax advice. We do not represent you before the assessor, we do not attend hearings, and we do not negotiate on your behalf.
No promised outcome. Reductions are decided solely by your County Assessor on the evidence and the law. Our estimate is exactly that, an estimate. Nobody can promise you a reduction, and we do not.
The fee. A flat $29 per filing, charged when you file, not a share of your savings. Checking is free. If our analysis does not find savings worth claiming, we will not let you file and you will not be charged. The informal review itself is free at every county; you are paying us for the analysis, preparation and delivery, and you are free to do it yourself instead using the comparable sales we show you.
Accuracy of what you give us. The form is signed by you and submitted in your name. Please check it before signing. We build it from public records, which are occasionally wrong or out of date, and we will correct anything you spot.
Refunds. If we fail to deliver your filing to the county, we refund the fee. Email us.
Questions about any of this, or about your data, go to support@saveproptax.com. A real person answers.
If we change this page materially we will update the date at the top and, for changes that affect filings already made, email the people affected.
