Privacy Policy
Last updated: September 2026
1. Who We Are
PartyLine ("we," "our," or "us") operates the website mypartyline.org and related mobile applications. Our mission is to give voters a clear, accessible view of what their elected officials actually do.
2. Information We Collect
2.1 Information You Provide
| Data | Purpose | Required? |
|---|---|---|
| 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 |
| Ballot marks (races you mark on your sample-ballot worksheet, including candidate choices, "undecided," and "skip") | Show your own marked worksheet back to you | No — only if you use the worksheet, and only after you consent |
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 |
| Session ID and response ID for analytics correlation | Linking analytics events to survey sessions for product improvement | Automatically removed 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
4.1 What We Intend to Sell
PartyLine does not sell any data today. We intend to offer district-level aggregate statistics to political campaigns, advocacy organizations, researchers, and media outlets. We think a campaign that can see what the voters in a district actually want is a good thing for those voters. Such a figure is published only where a district has at least 100 verified responses, so it is always a count or an average across at least 100 people. 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"
As of the effective date at the bottom of this page, PartyLine has sold no data to anyone, and no payment method can be charged for data through the Service. Before the first sale we will change this section to say that sales have begun, and we will post a notice on the site. Until then, treat every sentence about selling here as a statement of intent, not of practice.
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 survey answers and your ballot marks counted in any aggregate figure we publish or offer for sale. Opting out takes effect immediately, and you keep the full use of PartyLine. There are four ways to do it:
- The switch in your account settings: sign in, open Account settings on the dashboard, and turn off "Include my answers in district aggregates". This is self-serve, it takes effect at once, and the same screen shows you which state you are in right now.
- If you have an account: email privacy@mypartyline.org from the email address on your account and ask us to exclude your responses.
- 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.
- Delete your account: deletion removes your responses and your ballot marks outright, so nothing of yours can enter a future aggregate. You can do this yourself from the same Account settings screen.
Global Privacy Control. If your browser or a privacy extension sends a Global Privacy Control signal, we read it and opt you out of aggregation automatically, without your having to ask. The account settings screen tells you when we have honored it. If your browser does not send the signal, nothing changes and we do not treat that as permission for anything.
Note: Opting out does not affect your ability to use PartyLine, and we will never ask you to give up a feature for it. A figure that has already been published cannot be un-published, because an aggregate holds no individual information to remove — but nothing of yours enters a new one after you opt out.
What opting out does not cover, said plainly: we still count how many people use PartyLine — how many surveys were completed on a given day, how many accounts exist, how many people came back a second time. Those are headcounts. They hold no answers, no district and nothing that identifies you, and they are not the district figures we publish or would ever offer for sale.
All of these controls, and a plain statement of what PartyLine does and does not sell today, are collected on one page: Do Not Sell or Share My Information.
5. Data Security
We implement industry-standard security measures:
- Encryption in transit: All data is transmitted using TLS 1.2 or later, with TLS 1.3 where your browser supports it
- 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
6.1 Right to Access
You can delete your account yourself: log in on the dashboard and choose “Delete account”, and your account and the data tied to it are removed from our database right away. A deletion requested by email instead is completed within 45 days (see 6.2). Copies in our database provider’s routine backups are not edited; they expire on the provider’s schedule. You can also request a copy of all data we have about you by emailing privacy@mypartyline.org.
6.2 Right to Delete
You can request deletion of your data at any time:
- If you have an account: Email privacy@mypartyline.org from the address on your account
- If you used PartyLine without an account: Email privacy@mypartyline.org with your approximate survey date, state, and ZIP code
We will acknowledge your request within 10 business days and complete deletion within 45 days. Note: We cannot delete data that has already been included in aggregate statistics, as it no longer contains any individual information.
6.3 Right to Correction
You can update your survey responses at any time by retaking the survey.
6.4 California Residents (CCPA)
If you are a California resident, you have additional rights:
- Right to know what personal information we collect
- Right to request deletion of your personal information
- Right to opt out of the "sale" of personal information
- Right to non-discrimination for exercising your rights
To exercise these rights, email privacy@mypartyline.org.
How a request is handled: send it to privacy@mypartyline.org from any address, and say what you want done. We aim to acknowledge every request within 10 business days and to complete it within 45 days, and we write to you if we need longer and say why. There is no charge for a request, we do not require you to create an account to make one, and we do not treat you differently for making one.
We honor the Global Privacy Control signal. If your browser or a privacy extension sends it, we treat you as opted out of aggregation automatically — you do not have to write to us, and we tell you in your account settings that we honored it.
Every one of these controls, including the self-serve opt-out switch, is collected on Do Not Sell or Share My Information, which also states plainly what PartyLine does and does not sell today. These commitments are ours voluntarily; we offer them because they are right, not because we have concluded that any particular statute applies to PartyLine today.
7. Data Retention
| Data Type | Retention Period |
|---|---|
| Survey responses | Until you request deletion |
| Account information | Until you request deletion |
| IP address hashes | 30 days |
| Browser information | 90 days |
| Browser-local survey state and comparison preferences | Until you clear browser data, reset the app, or overwrite the saved state on this device. This local state does not intentionally retain your raw full street address. |
| Ballot marks | Until you change or clear them; deleted automatically and immediately when your account is deleted |
| Aggregated statistics | Indefinitely (contains no personal data) |
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)
- Geocodio: Address geocoding — your address is sent to Geocodio to determine your congressional district (Privacy Policy)
- Stripe: Payment processing for premium subscriptions and optional support contributions (Privacy Policy)
- Resend: Transactional email delivery — if you opt in to email notifications, your email address and message content are processed by Resend to send those emails (Privacy Policy)
- Sentry: Crash and error reporting — while crash reporting is switched on, an error message and the place in our code it came from are sent to Sentry when the site or app hits a bug, so we can fix it. We strip street addresses, email addresses, IP addresses and login tokens before sending, we never send your survey answers, and errors from our address lookup are not reported at all (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.
11. Contact Us

|---|---|---|
| Authenticated session cookie (HttpOnly) | Keep you signed in across page loads | Up to 30 days unless you log out sooner |
| Survey state and match results (localStorage) | Save your progress and results on this device between page loads | Until you clear browser data, reset the app, or the saved state is overwritten |
