Privacy policy

Information we keep

When you create an account, we store your name, email address, email confirmation status and a hash of your password. We do not store your password as readable text. Sign-in sessions include a session token, expiry, IP address and browser user agent. We also keep information needed for email confirmation, password resets and sign-in rate limiting.

Your studies contain the property details you enter, such as its address, type, purchase price, land value, dates and optional tax rate; component descriptions, costs and classifications; and any photos, plans or documents you upload. We keep file names, types and sizes, along with saved document readings and the source information used in your study.

We use this information to run your account, protect access, prepare and save your studies, read the material you ask us to process and send account emails.

Private studies and files

NoCostSeg runs on Cloudflare. Account and study records are stored in Cloudflare D1, and uploads are stored in a private Cloudflare R2 bucket. The app checks ownership before returning a study or file: only its signed-in owner can open it through the app. Uploads are not published at public file links or made available to other account holders.

Private access does not mean that a file never leaves storage. Cloudflare processes data to operate the service, and the model features described below send the material you ask to have read to Anthropic. Hosting also produces operational logs used to diagnose errors.

Model-assisted reading and classification

When you use the model features, NoCostSeg sends component descriptions and relevant property-type context to Anthropic’s API to match components to the IRS tables. When you ask it to read an uploaded document, photo or plan, the file’s contents are sent to Anthropic’s API for reading. The returned facts, quotations and source references can be saved with your study.

These requests contain the study material and instructions needed for the task. They do not include your separate account record, password hash or session cookie. Personal information inside a document or component description is still part of the submitted material: a full document may include names, addresses or financial information. Only submit material you have permission to use, and remove information that is not needed before uploading.

This draft does not promise a particular retention period or training treatment for data processed by Anthropic. Those provider terms and the service’s retention arrangements must be confirmed before this policy is finalized.

Account email and optional Google sign-in

Email confirmation and password-reset messages are sent through Cloudflare Email Service. Cloudflare processes the recipient address and message contents to deliver them. The current service sends these account messages, not advertising emails.

If “Continue with Google” is offered and you choose it, Google handles that sign-in step and supplies the profile and authorization information needed to create or access your account. Email-and-password sign-in is also available.

Cookies and tracking

We use necessary cookies to keep you signed in and support account authentication. Sessions are configured to last up to 30 days and can be renewed as you use the service. Signing out ends that session. Blocking these cookies prevents signed-in features from working.

The site has no advertising or analytics trackers. We do not sell your information or share it with advertisers. The service integrations described above support hosting, account access, account email and the model features; studies are not automatically sent to a tax preparer or a partner.

Keeping, changing and deleting information

The current app keeps saved studies and uploads until you delete them; it does not automatically expire them. You can edit property details and remove components, files or an entire study. Deleting a file or study removes the corresponding active records and requests deletion of the associated uploads from the private bucket.

Deleting a study does not delete your account. There is not yet a self-service account deletion screen. Account deletion and privacy-request procedures, backup and log retention periods, and any applicable privacy-rights information remain to be finalized. The contact details below are placeholders and cannot yet be used to submit a request.

About this draft

This page will need to be updated as the service and its operating details are finalized. The Terms of use explain what a software-prepared study is for and what you and your tax preparer need to review.
