Last updated on: Februray 12th, 2026

This Privacy Policy describes how Missive, owned and operated by Heliom inc. (collectively, “Missive”, “Heliom”, “we”, “us”, or “our”), collects, uses, secures and shares data collected from users (“Users”) of the Missive application (“App”). The “App” means all websites, products and services offered by us, including without limitation missiveapp.com, mail.missiveapp.com and downloadable applications offered at missiveapp.com/download.

Personal Data We Collect

For Users only browsing our website (missiveapp.com), we collect the following information:

  • Browser and device data, such as operating system and browser name, screen dimensions, device manufacturer.
  • Usage data, such as time spent on our website, pages visited, and the pages that led or referred Users to our website.
  • We do NOT collect or store any data if a visitor has Do Not Track enabled.

In addition, we collect the following information from Users who register to the App:

  • Account activity, such as account sign-ups and subscription activity;
  • Account information, such as email address, password or third-party login token;
  • User contact information, such as name, mailing address and phone number. We collect only the User’s own contact information and do not collect any User’s contact list or address book;
  • Data imported from Users external channels, such as emails, address book contacts, calendar events, SMS and other messaging data stored in services, such as Gmail, Office 365, IMAP, Twilio, Instagram, WhatsApp, Threads, Facebook, Asana, Pipedrive and Todoist;
  • Data created by Users from within Missive, such as chat comments, uploaded files and messages sent to external channels;
  • Internet Protocol (IP) address.

We collect personal data from Users only if they voluntarily submit such data to us. Users can always refuse to supply personal data, although this may prevent them from using related App features.

If we collect personal data not expressly identified above, we will process it in accordance with this Privacy Policy or as otherwise disclosed at the time it is collected.

Certain information we collect automatically is obtained through cookies and other tracking technologies, like web beacons (sometimes called “tracking pixels” or “clear GIFs”). We may use first-party cookies or third-party cookies to collect personal information, or any other type of information that becomes personal information when combined with other information. The types of cookies that we may use include, but are not limited to, the following:

  • Essential Website Cookies: These cookies are strictly necessary to provide you with services available through the App and to use some of their features, such as access to secure areas.
  • Performance And Functionality Cookies: These cookies are used to enhance the performance and functionality of the App but are non-essential to their use. However, without these cookies, certain functionalities (like videos) may become unavailable.
  • Analytics and Customization Cookies: These cookies collect information that is used either in aggregate form to help us understand how the App is being used or how effective our marketing campaigns are, or to help us customize the App for you.
  • Targeting and Advertising Cookies: These cookies are used to make advertising messages more relevant to you. They perform functions like preventing the same ad from continuously reappearing, ensuring that ads are properly displayed for advertisers, and in some cases selecting advertisements that are based on your interests. These cookies may also be used to track interactions with the App, allowing third-party advertisers to measure the effectiveness of their campaigns and optimize the targeting of their advertisements.

How We Use Personal Data

Missive does not sell personal data to third parties. We collect data to provide an App that lets Users manage the data in question. For non-registered Users, we limit the personal data we collect to what is necessary for operating, securing, measuring, and marketing the App.

We will not transfer any Users’ data to others unless doing so is necessary to provide and improve the App’s functionality in accordance with this Privacy Policy, comply with applicable law, or as part of a merger, acquisition, or sale of assets.

Examples of how we use collected data to offer App functionality include:

  • Synchronizing data from Users external channels to be displayed in the App’s interface. Data synchronization happens continuously, regardless of Users being online (actively using the App) or offline, for purposes such as sending notifications to Users mobile devices. After a continuous period where a User does not actively use the App, we stop synchronizing their data.
  • Delivering data to Users external channels, only as explicitly requested by Users. Data delivery may happen immediately upon Users request, at a later date scheduled by Users, or automatically upon events such as an incoming message (auto-responders) in accordance with Users chosen parameters.

In addition to providing our App’s main functionality, we may use Users personal data for the following purposes:

To improve customer service

Personal data helps us respond to customer service requests and support needs more efficiently.

To influence our App’s direction and features

We may use data in aggregate to understand how our Users as a group use the services and resources provided on our App.

To improve our App

We may use feedback Users provide to improve our products and services.

To process payments

All payments made through the App, including the storage of credit card data for the duration of the User’s subscription to facilitate recurring payments, are handled and processed by our payment service provider, Stripe, which is certified as a Payment Card Industry (PCI) Level 1 Service Provider. 

To send periodic emails

We may use email addresses to send Users’ data and updates pertaining to their usage of the App. It may also be used to respond to their inquiries, questions, and/or other requests.

Missive’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.

For targeted advertising

Our third-party advertising partners may receive information about user interactions with the App and our communications collected over time and across different browsers and devices through cookies and similar technologies such as web beacons. The information collected through these technologies may include online identifiers and other information that can be considered personal data under applicable data protection laws.

These third-party advertising partners may use information about your visits to the App and other websites to provide relevant advertisements about goods and services that you may be interested in.

This information supports the delivery, measurement, and optimization of advertising campaigns, including conversion tracking and attribution. Such processing is carried out only through the use of cookies or similar technologies, and where required by law, is subject to your consent.

How We Store And Protect Personal Data

Missive being a collaborative application, Users’ data is stored on our servers. This allows Users to access their data from different devices or locations and also to easily share their data with other Users.

We do not allow humans to read Users personal data, unless:

  • We first obtained the User’s affirmative agreement for specific messages or data;
  • It is necessary for security purposes (such as investigating a bug or abuse);
  • It is necessary to comply with applicable law; or
  • Our use is limited to internal operations and the data (including derivations) have been aggregated and anonymized.

How We Share Collected Data

We do not sell, trade, or rent Users personal data to others. We may use third-party service providers to help us operate our business and the App or administer activities on our behalf; these companies are authorized to use Users personal data only as necessary to provide these services to us:

  • Email communications. We use third-party providers to send Users emails related to their usage of Missive, such as invites, password resets and new feature announcements. As part of this, Users email addresses and limited personal data, such as name and company name, are shared with these email service providers.
  • Cloud computing infrastructure. We do not manage physical servers ourselves, so we host the App and Users’ data in third-party data centers. All data we store uses encryption-at-rest to strengthen security within the provider’s premises. You can read more about our security practices here.
  • Payment processing. We delegate the processing of credit card payments to a certified third-party provider. This provider stores Users credit card and billing information as necessary to process recurring payments and generate related invoices, receipts and credit notes.
  • Community management. We use a third-party provider to host our roadmap and feature planning forum. Users can optionally connect to this platform to suggest, comment and upvote feature requests. As part of this process, Users email address and name are shared with the third-party platform.
  • Error reporting. We use a third-party provider to track software bugs happening to logged in Users. The email address of affected Users is shared with the provider so our engineers can associate bugs to Users and provide a fast and appropriate response. Thirty days following the occurrence of a bug, Users’ data is deleted from the provider’s storage.
  • Advertising. We work with third-party advertising providers in connection with targeted advertising activities. In this context, personal data may be collected by, or disclosed to, these providers, including those that deploy third-party advertising cookies. These third parties process such data in accordance with their own privacy policies.

All third-party providers described above are listed as subprocessors on our GDPR page.
