SignaPipe

Privacy policy

Effective date: October 5, 2026

SignaPipe (“SignaPipe,” “we,” “us,” or “our”) is a follow-up CRM for independent contractors and solo professionals. It helps you stay in touch with the people who matter to your business by organizing your relationships, drafting follow-ups, and reminding you when it’s time to reach out. This Privacy Policy explains what information we collect, how we use it, who we share it with, and the choices you have. It applies to the SignaPipe web application and related services.

1. What we collect

We collect the following categories of information:

  • Account information. Your email address and name, which you provide when you create an account.
  • Your relationships and contacts. The people and contacts you add to SignaPipe, along with details you record about them (such as company, role, and how you know them).
  • Activity you create. The touches, drafts, notes, and other content you generate as you use the service to manage your follow-ups.
  • Email account data (only if you connect an email account). If you connect Gmail, Outlook / Microsoft 365, Yahoo Mail, or iCloud Mail, we access that mailbox to power the features you use. Sections 2 to 4 describe exactly what we access for each provider.
  • Other integrations you choose to connect. If you connect tools such as Google Calendar, Calendly, QuickBooks, or a Stripe account for revenue tracking, we access the data those features need (for example, your meetings or the payments tied to your contacts).
  • Technical and essential data. Basic information needed to operate the service securely, such as authentication tokens and minimal logs.

Across every email provider, we do not store the content of your emails. Most features use only who sent or received a message, when, its subject line, and a short text preview. When you open an email with one of your contacts in SignaPipe, we fetch that full email, and any attachment you choose to download, directly from your mailbox to show it to you; we don’t keep a copy (attachments larger than 4 MB are held in private, temporary storage for up to 15 minutes so your browser can download them, then deleted). Images from the internet in those emails stay blocked until you choose to show them. The only email information we store is a short preview of replies you receive from your contacts, saved on that contact’s activity so you can see they replied. Inbox and email-history analysis results are not stored on our servers; you choose which people to add as contacts.

2. Google data and Limited Use

If you connect your Google account, we access the following through Google APIs, solely to provide the features you use:

  • Gmail (send and read). Sending the follow-ups you approve from your own Gmail address; detecting replies from your contacts so we can update your follow-up status; analyzing who you email and when, to suggest people to reconnect with; and showing your emails with a contact, in full when you open one.
  • Google Calendar (view and manage events). Showing your upcoming meetings and creating or updating appointments you schedule through SignaPipe.
  • Google Contacts / People (read-only). Importing your saved contacts and “other contacts” (people you’ve emailed) when you choose to import them.

SignaPipe’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

In keeping with those requirements, we:

  • Do not use Google user data for advertising.
  • Do not sell Google user data.
  • Do not transfer Google user data to others except as needed to provide or improve these user-facing features.
  • Do not use Google user data to develop, improve, or train generalized AI or machine-learning models.
  • Do not allow humans to read Google user data, except with your consent, for security purposes, to comply with applicable law, or as required for internal operations in accordance with the Google API Services User Data Policy.

3. Microsoft (Outlook / Microsoft 365) data

If you connect a Microsoft account, we access it through Microsoft Graph with the permissions you approve on Microsoft’s consent screen, solely to provide the features you use:

  • Mail (send and read). Sending the follow-ups you approve from your Outlook address; detecting replies from your contacts; analyzing who you email and when, to suggest people to reconnect with; and showing your emails with a contact, in full when you open one.
  • Contacts (read-only). Importing your Outlook contacts when you choose to.
  • Your basic profile. Identifying which mailbox is connected.

We never delete or change messages in your mailbox. The same commitments listed for Google data above (no advertising, no sale, no AI model training, no human reading except as described) apply to Microsoft data.

4. Yahoo Mail and iCloud Mail data

Yahoo Mail and iCloud Mail are connected with an app password that you create in your Yahoo or Apple account, never your regular password. We use it only to:

  • Read your mailbox (inbox and sent mail) to see who you email and when, to detect replies from your contacts, and to show your emails with a contact, in full when you open one. Mailboxes are opened read-only, so we don’t mark messages as read.
  • Send the follow-ups you approve from that address. For iCloud, we also save a copy of each email you send to your Sent folder, because iCloud doesn’t do this automatically.

Apart from that Sent copy, we never delete, move, or change anything in your mailbox. Your app password is encrypted before it is stored, and you can revoke it at any time in your Yahoo or Apple account, which immediately cuts off our access. The same commitments listed for Google data above apply to Yahoo and iCloud data.

5. How we use your information generally

We use the information we collect to:

  • Provide, maintain, and improve the SignaPipe service and its features.
  • Draft and send follow-ups, surface reminders, and organize your relationships.
  • Authenticate you and keep your account secure.
  • Respond to your support requests and communicate about the service.
  • Comply with our legal obligations and enforce our terms.

AI drafting. When SignaPipe drafts a message or summary for you, we send the relevant context, such as the contact’s details and your recent interactions (which can include reply previews from your email), to one of our AI providers listed below to generate the text. We use these providers’ business APIs, and we do not use your data to train AI models.

6. Sub-processors and sharing

We use a small set of trusted service providers to operate SignaPipe. Each processes data only to provide their part of the service:

  • Vercel — application hosting.
  • Supabase — database, authentication, and storage.
  • Anthropic — AI drafting of follow-up messages.
  • OpenAI — AI drafting and summaries, optional voice-note transcription, and audio briefings.
  • Google (Gemini) — AI drafting and summaries, including as a backup when another AI provider is unavailable.
  • Stripe — billing and payment processing.
  • SendGrid — transactional and service email.
  • Twilio — optional SMS / WhatsApp messaging.

When you connect an email account or another integration (Google, Microsoft, Yahoo, Apple iCloud, Calendly, QuickBooks, or Stripe), we exchange data with that provider on your behalf, as described above. Those providers handle your data under their own privacy policies.

We do not sell personal data. We may disclose information if required by law, to protect the rights and safety of SignaPipe and our users, or in connection with a business transfer, in each case consistent with this policy.

7. Security

We protect your data with encryption in transit and at rest. Access tokens for connected accounts and app passwords for Yahoo and iCloud are encrypted with AES-256 before they are stored, and connections to email providers use verified, encrypted (TLS) connections. We apply row-level access isolation so that each user can only access their own data. No system is perfectly secure, but we work to safeguard your information using industry-standard measures.

8. Retention and deletion

We retain your information for as long as your account is active or as needed to provide the service.

  • Disconnecting an email account in Settings → Integrations deletes the access tokens or app password we stored for it and stops all access. Contacts you chose to add, and reply previews already saved on them, stay in your account until you delete them.
  • Email-history analysis results are kept only in your own browser, on the device where you ran the analysis, so you can review them later. Clearing your browser data removes them.
  • Deleting your account removes your data, including data derived from your connected accounts (such as imported contacts, reply previews, and cached calendar information).

To request deletion, email privacy@signapipe.com, and we will process your request.

9. Your rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to object to or restrict certain processing. You can exercise many of these rights directly in the app, or by emailing privacy@signapipe.com.

You can disconnect any email account at any time in Settings → Integrations. You can also revoke access from the provider’s side: in your Google account permissions, in your Microsoft account’s app permissions, or by deleting the app password you created in your Yahoo or Apple account.

10. Cookies and essential storage

SignaPipe uses cookies and similar browser storage that are essential to operate the service, such as keeping you signed in and remembering your email-history analysis results on your device. We do not use advertising or cross-site tracking cookies.

11. Children

SignaPipe is not intended for anyone under 18 years of age. We do not knowingly collect personal data from children. If you believe a minor has provided us data, please contact us so we can remove it.

12. International transfers

SignaPipe and our service providers may process and store data in countries other than the one in which you live. Where we transfer personal data internationally, we take steps to ensure it remains protected consistent with this policy.

13. Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the effective date above and, where appropriate, notify you within the service. Your continued use of SignaPipe after an update means you accept the revised policy.
