Privacy Policy

Version: privacy-v1  ·  Effective: 2026-05-27  ·  Jurisdiction: United States
Privacy is not a legal obligation we begrudgingly fulfill. It is a design principle we built this service around. We store the minimum required to send you useful signals. We never sell your data. We never will.

01 — Who This Applies To

This policy applies to all users of Their Signals at theirsignals.ai, operated by Otter Tail Heavy Industries LLC. It explains what data we collect, why we collect it, how we store it, and what rights you have over it.

02 — What We Collect

We collect only what we need to deliver the service. Here is the complete picture:

Data Stored? Format Why
Email address YES Encrypted at rest Signal delivery and account access
Tier / subscription status YES free / paid / pro Determine which signals you receive
Path preference YES Easy / Medium / Hard Route appropriate signals
Signal frequency preference YES Integer (1–8 schedule) Deliver signals on your schedule
Ticker symbols YES Symbols only (e.g. VOO, KO) Personalize signals to your holdings
Allocation ranges YES Ranges only (e.g. $10k–$50k) Calibrate signal relevance
Account numbers NEVER Stripped before storage Not needed, not wanted
Institution name NEVER Stripped before storage Not needed, not wanted
Legal name NEVER Never requested or stored
Exact dollar amounts NEVER Converted to ranges Ranges are enough; precision is a liability
SSN or tax ID NEVER Never requested under any circumstance
Original account statements NEVER Deleted immediately after anonymization We anonymize and discard; we never log originals
Payment card data NEVER Handled by Stripe We never see or touch your card details
The anonymization rule: If it could identify a person or account — it never enters our database. We store the financial picture. Never the person behind it.

03 — How We Collect It

We collect data through three channels:

We do not use tracking pixels, advertising cookies, or behavioral analytics. We do not fingerprint your browser or device.

04 — How We Use It

We use your data for one purpose: delivering the service you signed up for.

We do not use your data to build advertising profiles, train AI models on your personal financial information, or sell to third parties under any circumstances.

05 — Where Data Lives

Your data is stored in a SQLite database on a Mac Mini located at our operator's home office in Columbus, Ohio. It is not stored in a public cloud database service.

The system is accessible via a Cloudflare Tunnel. Cloudflare provides DNS and tunnel services; they do not have access to your stored data.

Email is delivered via Gmail SMTP. Google's servers handle email transit. We do not store copies of sent signal emails beyond what Gmail retains as sent mail.

Payment processing is handled by Stripe. Stripe's privacy policy governs data they collect during payment. We receive confirmation of payment status only — no card details.

06 — Who We Share It With

We do not sell your data. We do not share your data with advertisers. We do not share your data with data brokers. Full stop.

The only parties who access your data are:

07 — Cookies and Tracking

We use session tokens stored in your browser's local storage to keep you signed in after OTP verification. These are functional only — they are not used for tracking or advertising.

We do not use third-party analytics services (Google Analytics, Mixpanel, etc.). We do not use advertising cookies. We do not participate in ad networks.

If you clear your browser storage, you will need to verify your email again to access your dashboard.

08 — Your Rights

You have the following rights over your data:

To exercise any of these rights, email [email protected]. We will respond within 30 days.

Account deletion removes all stored data associated with your email address. Anonymized aggregate data (not linked to you) may be retained.

09 — Data Retention

We retain your data as long as your account is active. If you cancel or request deletion, your data is removed within 30 days.

We do not retain financial documents or statements beyond the anonymization process. Original documents are deleted immediately after the anonymized result is extracted.

10 — Security

We take security seriously. Our practices include:

No system is perfectly secure. If you discover a security vulnerability, please report it to [email protected] before disclosing publicly. We will respond promptly.

11 — Children's Privacy

Their Signals is not directed at children under 18. We do not knowingly collect data from anyone under 18. If you believe a minor has provided us with data, contact us and we will delete it promptly.

12 — Changes to This Policy

We may update this policy. When we do, we update the version date above and, for material changes, notify you by email. Your continued use of the service after notice constitutes acceptance.

We will never change our core commitment: we do not sell your data, we do not share it with advertisers, and we store only what we need to serve you.
