This typically occurs when multiple Devices were used to record data simultaneously, and those Devices were assigned to the same account. ![](https://support.hexoskin.com/hubfs/Overlaps%20of%20records-png.png) The **rule of thumb** is that for a recording session, **each and all of the Hexoskin users have to have their own Hexoskin account** and a **Hexoskin Device assigned to their personal account**. ![](https://support.hexoskin.com/hubfs/no%20overlaps-png.png) This is very important as the demographic information provided upon account creation is essential for the calculation of different metrics on the Hexoskin servers. Synchronizing data from multiple users in the same account can lead to inaccurate metrics.  It's important to follow some specific steps to prevent future overlaps: 1. Make sure that each Hexoskin user has their own account 2. If the recording Device is shared with different users (e.g. Device used by user # 1 is loaned to user # 2), make sure the recording Device is assigned to the correct account/user before starting a recording session (e.g. the Device must now be assigned to user # 2). If you omit this step, the new recording session will end up in the previous user's account. If you are using Hexoskin in a research or project setting with multiple users to manage, learn how to easily create accounts for your participants by following the procedure described in the following article: [Managing Multiple Users for a Research Project](https://support.hexoskin.com/managing-multiple-users-for-a-research-project-my.hexoskin.com?hsLang=en) To address records in overlap, please contact our support team at support@hexoskin.com and include details about the record such as the date, start time, duration and user (email address) the record is assigned to. We'll provide you with some options and make any necessary changes to allow you to move forward with your data collection.  - [Hexoskin OneSync Software](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#main-content) - [Hexoskin OneSync Advanced Features](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#hexoskin-onesync-advanced-features) - [Hexoskin OneSync Basics](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#hexoskin-onesync-basics) - [Hexoskin Data Analysis](https://support.hexoskin.com/hexoskin-data-analysis?hsLang=en) - [Hexoskin Support Topics](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#main-content) - [Hexoskin Mobile App](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-mobile-app) - [Hexoskin Articles](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-articles) - [Hexoskin Set-up and Configuration](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-set-up-and-configuration) - [Hexoskin Recorder](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-recorder) - [Hexoskin Troubleshooting](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-troubleshooting) - [Hexoskin FAQ](https://support.hexoskin.com/hexoskin-faq?hsLang=en#main-content) - [Frequently Asked Question for the Hexoskin community](https://support.hexoskin.com/hexoskin-faq?hsLang=en#frequently-asked-question-for-the-hexoskin-community) - [Order](https://support.hexoskin.com/hexoskin-faq?hsLang=en#order) - [Hexoskin OneView dashboard](https://support.hexoskin.com/hexoskin-oneview-dashboard?hsLang=en) - [Hexoskin OneSync](https://support.hexoskin.com/hexoskin-onesync?hsLang=en) - [Hexoskin Smart Garments](https://support.hexoskin.com/hexoskin-smart-garments?hsLang=en#main-content) - [Hexoskin Device](https://support.hexoskin.com/hexoskin-smart-garments?hsLang=en#hexoskin-device) - [Hexoskin App](https://support.hexoskin.com/hexoskin-app?hsLang=en) - [Hexoskin Dashboard](https://support.hexoskin.com/hexoskin-dashboard?hsLang=en) - [Help for Developers](https://support.hexoskin.com/help-for-developers?hsLang=en) - [Ordering Your Hexoskin](https://support.hexoskin.com/ordering-your-hexoskin?hsLang=en) - [Hexoskin Support](https://support.hexoskin.com/hexoskin-support?hsLang=en) [![Hexoskin - Logo - No Tagline - Rectangle - White - Transparent-Nov-28-2023-04-38-48-1716-PM](https://support.hexoskin.com/hs-fs/hubfs/Hexoskin%20-%20Logo%20-%20No%20Tagline%20-%20Rectangle%20-%20White%20-%20Transparent-Nov-28-2023-04-38-48-1716-PM.png?width=200&height=50&name=Hexoskin%20-%20Logo%20-%20No%20Tagline%20-%20Rectangle%20-%20White%20-%20Transparent-Nov-28-2023-04-38-48-1716-PM.png "Hexoskin - Logo - No Tagline - Rectangle - White - Transparent-Nov-28-2023-04-38-48-1716-PM")](https://hexoskin.com) 5800, Saint-Denis, Suite 601, Montréal (Québec), Canada Copyright © 2026, Hexoskin
