Privacy policy

1. Browser-first processing (SF-11)

When you use our Average Stay Checker, your raw Airbnb or VRBO booking CSV files are parsed 100% inside your web browser. They are never uploaded to our servers unless you explicitly click “Save to my account.” Similarly, we never put your income, property price, or email address into URL query strings (SF-10).

2. What we store when you opt in

If you submit your email for a worksheet, book a Founding 10 call, or sign in to the Material Participation Log, we store the following in Google Cloud Firestore:

• Your account: the name, email address, and account ID that Google sign-in gives us.
• Your log: the Properties you name, the people you add (their names, roles, and whether they are paid to manage), your log entries (date of work, hours, category, description, and the evidence source for an outside worker’s hours), the history of every edit, and any Groupings you record.
• Reminder settings, if you turn them on: how you want to be reminded (email, text, or both), the day, how many idle days before a reminder, your time zone, your mobile number if you choose texts, and a record of your text consent (when you gave it and which wording you saw).
• Contact details and tool outputs you submit with a worksheet or call request.

Some tools also remember your answers in your browser for the length of your visit so you do not have to retype them.

3. Who sees your data (SF-13)

Your Material Participation Log is scoped to your own signed-in account. Nobody else can view it. Your spouse’s hours are entered by you: a spouse does not have a separate login. If you opt into the Founding 10 offer, relevant property and participation workpapers are shared only with our cost segregation study provider, the reviewing CPA firm, and your designated CPA to deliver your engagement. We never sell or rent your data.

If you create a private share link for an estimate, anyone who has the link can see that estimate’s inputs (such as price and income) until it expires after 30 days or you revoke it. Share links never include your log.

4. Companies that handle data for us

We use a small number of service providers to run the site. They handle data only to provide their service to us:

• Google (Firebase Authentication, Cloud Firestore, and Cloud Functions) for sign-in, storage, and the scheduled job that sends reminders.
• Twilio SendGrid delivers reminder emails. It receives your email address and the reminder text.
• Twilio delivers reminder texts. It receives your mobile number and the reminder text.

A reminder never includes your hours, your tax status, or your property details. Our logs record only counts of how many reminders were sent, not addresses, numbers, or message text.

5. Email and text reminders

Reminders are optional and are sent only to the account owner. You choose email, text, or both, the day of the week, and how many days without a new entry must pass first. We send at most one reminder a week, around 9:00 am in your time zone, and only if you have not logged anything for the number of days you chose.

We send texts only after you tick the consent box next to the number you enter, and we keep a record of when you did. Consent to texts is not a condition of using the site. You can stop texts at any time by replying STOP to any message, by choosing email only in your reminder settings, or by turning reminders off. Reply HELP for help. Message and data rates may apply.

No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent are not shared with any third parties.

The full text message terms are in our Terms of Service.

6. How long we keep it

We keep your account and log until you delete them. If you turn reminders off, we keep your settings so you can turn them back on; choose email only to remove your mobile number from your settings, or delete your account to remove everything.

7. How to delete your account and all data in one click (SF-12)

When signed into the Material Participation Log (/log), click the “Delete account & all data (SF-12)” button in the top bar. That single click permanently deletes your Firestore household documents, properties, log entries, revisions, reminder settings (including your mobile number and consent record), and authentication record. You can also request deletion anytime by emailing advisors@shorttermrentaltaxes.com.
