Mist is a food and health journal operated by Holograph, a general partnership based in Ontario, Canada. This policy explains how we collect, use, disclose, retain, and protect personal information when you use the Mist apps or getmistapp.com.
Mist is ad-free and built by founders from Canada and Europe who actually care about privacy, and actually care about making Mist a delighful, genuinely-useful product. Our commitments are simple:
We take questions and concerns seriously. If anything in this policy is unclear, or if you want to ask how Mist handles your information, email us at support@getmistapp.com, or tap "Send feedback" in the app settings to reach us directly.
We use information to:
Mist uses AI to interpret entries and photos, estimate nutrition, provide assistant responses, and support related search features. For these purposes, we may send our AI and search providers the entry, photo, barcode, or message you submit, together with relevant journal history, assistant history, saved profile or goals, and language, country, or time-zone preferences needed to produce a useful result.
We do not intentionally include your account name or email address in requests sent to AI providers. However, information you type or include in a photo may itself identify you. Our AI providers process this information to provide Mist's features and are not permitted by us to use it to train their models. Holograph does not use your content to train or fine-tune its own AI models.
Authorized personnel may review journal or assistant content when reasonably necessary to investigate a user-reported problem, diagnose a serious technical failure, conduct a safety, abuse, or fraud investigation, or perform product-quality review and improvement.
Nutrition estimates and assistant responses are generated by software and may be incomplete or wrong. Mist is not a medical service, and its output should not be relied on for medical diagnosis, treatment, or other clinical purposes.
Depending on how you use Mist, consumer health data may include your journal entries, photos, assistant conversations, optional profile and goals, information imported from Apple Health or Health Connect, and nutrition or health-related information derived from them. We obtain this information from you, from a connected health service at your direction, or by deriving it through Mist's features.
We use this information to provide and personalize Mist, analyze entries and photos, calculate nutrition, sync data you choose to sync, answer questions, troubleshoot the service, protect against misuse, and improve product quality. We do not sell consumer health data, use it for advertising, provide it to data brokers, or use it to build advertising profiles.
You control whether Mist can access Apple Health or Health Connect through your device permissions and Mist's settings. Disabling a connection stops future syncing but does not automatically remove data already imported into Mist. Information Mist previously wrote to Apple Health or Health Connect is controlled through that platform and is not necessarily removed when you delete it from Mist.
We do not sell personal information and do not use it for third-party advertising. We disclose information only as described below:
Holograph does not have affiliates with which it shares consumer health data. Depending on the feature you use, the service providers described above may process journal entries, photos, assistant messages, optional profile information, connected health-platform data, or derived health and nutrition information. Other categories of third parties that may receive consumer health data are business successors, authorities, and other parties in the circumstances described above.
We generally retain account information and user content while your account exists. Operational logs, diagnostics, feedback, and support correspondence are retained only for as long as reasonably necessary for the purposes described in this policy. We may retain limited transaction, fraud-prevention, dispute, or legal records when required for accounting, tax, refunds, chargebacks, security, or legal claims. These limited records do not include your journal.
Uploaded photos are generally retained until the associated account is deleted or we complete an applicable deletion request.
You can delete your account from Settings or request deletion by emailing support@getmistapp.com from the address associated with your account. We delete account data from active systems within 30 days. Residual copies may remain in restricted backups until those backups are overwritten according to our normal backup schedule. If a backup is restored, deletion requests are reapplied before the restored data is returned to normal use.
Deletion does not require us to delete information that has been irreversibly de-identified or aggregated so that it can no longer reasonably be linked to you. We may also retain information where and for as long as applicable law permits or requires.
You can download journal data using the export tools available in Settings.
We use administrative, technical, and organizational safeguards designed to protect personal information. Data is encrypted in transit, and databases and stored files are encrypted at rest. Production access is protected by multi-factor authentication and restricted according to role and operational need. We review our security and privacy practices regularly. No method of storage or transmission is perfectly secure.
Depending on where you live, you may have rights to confirm whether we process your information; access, correct, or obtain a copy of it; request deletion; withdraw consent from future optional processing; object to or restrict certain processing; and complain to a privacy or data-protection authority. You may exercise these rights through Settings where available or by emailing support@getmistapp.com. We may need to verify your identity before completing a request. We will not discriminate against you for exercising a privacy right.
You may also ask which categories of third parties received your consumer health data. If we deny a privacy request, you may reply to our decision and ask us to reconsider it. You may contact the appropriate regulator if you remain dissatisfied.
Where applicable law requires a legal basis, we process information as needed to provide the service you request, based on your consent for optional features such as health-platform connections, for our legitimate interests in securing, supporting, and improving Mist, and to comply with legal obligations. You may withdraw consent for future processing, but withdrawal does not affect processing already carried out lawfully.
Holograph is based in Canada, and Mist's primary servers and storage are located in the United States. Information may also be processed in other countries where our service providers operate. Those countries may have different privacy laws from your country. We use contractual and other safeguards where required for international transfers.
Mist is intended for users aged 13 and older and is not directed to children under 13. If the law where you live requires you to be older to consent to the processing described in this policy, you must meet that age to use Mist. If you believe a child is using Mist contrary to this section, contact us and we will take appropriate action.
We may update this policy as Mist or applicable requirements change. We will update the date at the top and provide additional notice in the app when a change is material.
Holograph is responsible for the personal information described in this policy. Questions, requests, or complaints may be directed to our Privacy Officer at support@getmistapp.com.
