Privacy Policy

Last updated: March 2026

      The Short Version: We collect your survey responses and location data needed to match you with politicians. If you enter a full street address, we use it transiently to determine your congressional district more accurately, then retain only derived location fields such as state, district, and ZIP code. We only publish or sell aggregated district-level data from account-linked respondents once minimum sample thresholds are met. We never sell individual data.
    

1. Who We Are

PartyLine ("we," "our," or "us") operates the website mypartyline.org and related mobile applications. Our mission is to help voters understand how politicians actually vote on issues they care about.

2. Information We Collect

Email address	Account creation and communication	Only for accounts
State and congressional district	Show your representatives and candidates	Yes
Street address (transient lookup only)	Determine your congressional district accurately	Yes, during address lookup
ZIP code	Retained as part of your derived location record	Yes
Survey responses	Match you with politicians, generate aggregates	Yes

2.2 Information Collected Automatically

Data	Purpose	Retention
IP address hash	Fraud prevention and duplicate-submission detection; we do not store the raw IP address	30 days
Browser information (user agent and referring page URL)	Bot detection, abuse investigation, and troubleshooting	90 days
Session-level analytics events (event name, page path, feature usage)	Product improvement and understanding how people use PartyLine	Event data retained indefinitely; user-identifiable fields (user ID, session ID, ZIP code) automatically removed after 90 days
State, district, and ZIP code associated with survey responses	Matching you with local representatives and generating aggregate district statistics	Retained with survey response; ZIP code removed from analytics after 90 days

2.3 Information We Do NOT Collect

Your name (unless you create an account and provide it)
Your GPS coordinates
Your phone number
Demographic information (age, race, gender, income)
A persistent device fingerprint or device identifier
Your browsing history outside our site

We do not retain your raw full street address in long-term browser storage or in our survey-response records. We keep only the derived location fields needed to operate the service, such as state, district, ZIP code, and location accuracy metadata.

3. How We Use Your Information

Provide the service: Match you with politicians based on your survey responses
Improve the product: Understand how people use PartyLine
Generate aggregated insights: Create district-level statistics (see Section 4)
Communicate with you: Send account-related emails (if you have an account)
Prevent fraud: Detect bots and duplicate submissions

4. Data Aggregation and Sale

      Important: We sell aggregated data with user-identifiable fields removed. We NEVER sell individual responses, and we NEVER share data that could identify you personally.
    

4.1 What We Sell

We sell district-level aggregate statistics to political campaigns, advocacy organizations, researchers, and media outlets. For example:

"68% of verified respondents in PA-04 support expanding healthcare access"
"Climate policy is the #2 priority issue among verified respondents in CA-12"

4.2 What We Never Sell

Individual survey responses
Email addresses or any contact information
Data from districts with fewer than 100 verified responses
Any data that could identify a specific person

4.3 Your Right to Opt Out

You can opt out of having your responses included in aggregate products. To opt out:

If you have an account: Email privacy@mypartyline.org from the email address on your account
If you used PartyLine without an account: Email privacy@mypartyline.org with your approximate survey date, state, and ZIP code so we can locate the response

Note: Opting out does not affect your ability to use PartyLine.

5. Data Security

We implement industry-standard security measures:

Encryption in transit: All data transmitted using TLS 1.3
Encryption at rest: Our database provider (Supabase) encrypts all data at rest using AES-256 encryption
Access controls: Only authorized personnel can access raw data
IP hashing: We never store your raw IP address
Retention cleanup: Our application periodically clears stale IP hashes after 30 days, stale browser/referrer data after 90 days, and user-identifiable analytics fields after 90 days
Security practices: We follow security best practices and continuously improve our security posture

6. Your Rights

8. Third-Party Services

We use the following third-party services:

Supabase: Database and authentication (Privacy Policy)
Vercel: Website hosting (Privacy Policy)
Cloudflare: Security and DNS (Privacy Policy)
Google Maps Platform: Address autocomplete — your typed address is sent to Google to provide suggestions (Privacy Policy)

9. Children's Privacy

PartyLine's general consumer product is intended for users 18 years and older. We do not knowingly collect personal information from children under 13.

Classroom Mode: PartyLine offers a dedicated Classroom Mode for use in educational settings under educator supervision. Student participation does not require names, email addresses, or accounts. Responses are stored with a random identifier and cannot be traced back to individual students by PartyLine or educators. Aggregated classroom results are only displayed when 5 or more students have participated, preventing individual identification. Educators must acknowledge our classroom privacy policy before creating a class.

If you believe a child under 13 has provided personal information outside of Classroom Mode, please contact us at privacy@mypartyline.org and we will promptly delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by:

Posting a notice on our website
Sending an email to account holders (for material changes)

Your continued use of PartyLine after changes constitutes acceptance of the updated policy.
