Scope
This policy covers the public website at jevumi.com and the Jevumi iOS app. Jevumi provides educational decision support for adult men considering or using a hair system. It is not a medical service, stylist certification program, booking service, or price quote.
Information stored on your device
The iOS app can store your System Finder answers and recommendation, including the alternative and reason codes; your saved Cost Plan; and your maintenance records, events, and check-ins. These records use Apple's local app storage on the device. They are not account records and are not synced by Jevumi to a user profile or Supabase.
The app does not ask you to create an account, upload photos, enter payment details, or provide a medical history. The website also has no Jevumi account, photo upload, payment, or purchase flow.
Location and ZIP Code
The iOS app requests location permission only after you choose Use My Location in the Stylist Finder. A ZIP Code you type and one-time location coordinates are used in memory to perform the search. The ZIP Code and one-time location coordinates are not saved as a user profile and are not sent to Supabase.
If you decline or restrict location permission, you can still search by ZIP Code. Apple and network infrastructure may process technical information needed to provide device location and network connectivity under their own terms.
Public stylist directory
The iOS app downloads public stylist directory information from Supabase, including source-linked public business details used for search and display. Jevumi does not send your System Finder, Cost Plan, maintenance, ZIP Code, or location coordinates to Supabase.
Directory coverage is limited, and public source information may be incomplete or change. An Unknown field means the available source did not confirm that item; it does not mean the business does not provide it. A listing is not a technical certification, endorsement, appointment, quote, or service-quality guarantee.
Network processing
When the website or app makes a network request, hosting, email, analytics, and database network providers may process technical information for transmission, reliability, abuse prevention, security, and troubleshooting. Jevumi does not claim that this necessary technical information can never appear in provider logs.
When the Jevumi iOS app downloads the public stylist directory, Supabase and its network infrastructure retain gateway request logs. Logs reviewed on September 5, 2026 included the client network address; request time, path, method, and response status; client environment information; and coarse location derived from the network address, including city, country, region, postal code, and time zone.
The postal code in these infrastructure logs is inferred from the network address; it is not the ZIP Code a user enters in the app. The network-derived location is approximate and is not precise device coordinates supplied through the phone's location permission.
The app does not send the ZIP Code a user enters, precise device coordinates, System Finder answers, saved Cost Plans, or maintenance records to Supabase. The public-directory request retrieves public stylist information, while necessary network metadata may still be processed and retained by the service provider.
The website System Finder
The website System Finder runs in your browser. Jevumi does not send its answers or recommendation category to its first-party measurement database or Google Analytics. The current website experience does not create an iOS app record.
Anonymous aggregate measurement on the website
On the canonical jevumi.com domain, Jevumi records a small set of fixed event counters to understand whether visitors read the Hair Fibers guides, move from those guides to Frontal Hair System guidance, open the System Finder, begin it, complete it, or open the recommended guide. Preview and alternate hostnames are excluded. Each counter is stored only as an event name, UTC calendar date, and total count.
These counters do not include self-check answers, recommendation category, names, email addresses, IP addresses, cookies, device identifiers, referrer details, full URLs, search queries, or free-form text. Jevumi does not use them to identify or profile a visitor. The measurement request is skipped when the browser exposes Global Privacy Control or a Do Not Track setting.
Google Analytics on the website
Jevumi uses Google Analytics 4 only after you select “Accept analytics cookies.” Before that choice, analytics storage, advertising storage, advertising user data, and advertising personalization are all set to denied, and the Google Analytics tag is not loaded. If you reject analytics, Jevumi does not send Google Analytics measurement requests or set Google Analytics cookies on a later page load.
After consent, Google Analytics measures page views and the standard interactions enabled for the web data stream through Enhanced Measurement. Depending on the interaction, this can include the page URL and title, previous page or referrer, session activity, scrolls, outbound link clicks, broad browser and device characteristics, and approximate geographic information. Jevumi does not send names, email addresses, self-check answers or result categories, Hair Profile information, photos, form content, diagnoses, or other user-entered health information to Google Analytics.
A connection to Google necessarily exposes the source IP address at the network layer. Jevumi does not add an IP address to an Analytics event or report. Google states that Google Analytics uses IP information for service security and approximate location processing. Google processes Analytics data to provide its measurement service under Google's applicable terms and privacy practices.
The Jevumi tag keeps advertising storage, advertising user data, and advertising personalization denied even after analytics consent. It also disables Google Signals and advertising-personalization signals in the page configuration. Jevumi does not install Google Tag Manager, connect this implementation to advertising or remarketing, set a User ID, or send custom self-check or form events to Google Analytics.
The current iOS app does not include Google Analytics, an advertising SDK, or a cross-app tracking SDK.
Email correspondence
If you choose to email Jevumi, we receive the sender address, message content, attachments, and technical headers included with the message. We use that information to review and respond to the inquiry, handle a correction or request, protect the mailbox from abuse, and maintain an operational record when reasonably necessary.
Email sent to hello@jevumi.com is routed through Cloudflare and delivered to a Google-hosted mailbox. Those providers may process the message to provide routing, spam filtering, security, storage, and delivery. Do not send scalp or face photos, medical records, diagnoses, detailed health histories, identification documents, payment information, or account credentials.
Website cookies and local storage
Jevumi stores your analytics choice in local browser storage so the website can remember whether you accepted or rejected analytics. This preference contains only “granted” or “denied.” It is not a profile and is not sent to the first-party measurement database.
If you accept, Google Analytics may set first-party cookies such as _ga and a property-specific _ga_* cookie to distinguish a browser and session for measurement. If you reject, the Google tag is not loaded on later page loads and Jevumi does not write those analytics cookies. Changing a previous acceptance to rejection also expires GA cookies visible to the site. You can review or change the choice through “Cookie settings” in the footer.
The hosting platform may use strictly necessary technologies for access control, security, or site operation. Browser and platform settings may also let you manage those technologies, but blocking necessary functions can affect access.
Accounts, photos, payments, advertising, and tracking
The current Jevumi website and iOS app do not provide a user account, photo upload, payment, subscription, or advertising feature. The app does not use data for cross-app tracking. The website uses only the first-party aggregate counters and consent-based Google Analytics described above.
Data retention and deletion
Finder, Cost, and Maintenance app data remains in local app storage until you remove it, uninstall the app, or the operating system otherwise removes app data. Device or cloud backup behavior is controlled by Apple and your device settings; Jevumi does not make an absolute promise about how a backup handles local app data.
- Finder: use Settings & About → Clear Finder Data to remove the eight-question draft and saved recommendation.
- Cost: use Settings & About → Clear Cost Plan to remove the saved cost plan.
- Maintenance: use My System → Clear My System Data to remove the current system, maintenance history, and check-ins.
Each control is separate. Clearing Finder does not remove Cost or Maintenance data; clearing Cost does not remove Finder or Maintenance data; clearing Maintenance does not remove Finder or Cost data. Uninstalling the app generally removes its local app container from the device, subject to Apple's operating-system and backup behavior.
The Finder, Cost, and Maintenance controls described above delete only their corresponding local records in the app. They do not directly erase infrastructure logs managed by Supabase or other service providers.
As of September 5, 2026, Supabase's published plan comparison states that the current Free plan provides one day of API and database log retention visible to the developer. This one-day developer-visible window does not mean that every platform log, backup, or internal security or operational record is deleted after one day. Supabase's complete provider-internal deletion schedule for this infrastructure data has not been verified by Jevumi.
Website email correspondence is kept only as long as reasonably needed for the inquiry, legal or security requirements, and basic operational records. You may request review or deletion through the Contact page, subject to information Jevumi must retain for legal, security, or abuse-prevention reasons.
Service providers
Jevumi uses its website hosting infrastructure to deliver and protect jevumi.com; Supabase to provide the app's public stylist directory; Cloudflare and Google for email routing and mailbox service; and Google Analytics for website measurement only after consent. These providers may process the limited information necessary to provide and secure their services under their own terms.
Jevumi does not sell personal information or share app Finder, Cost, Maintenance, ZIP Code, or location-coordinate data with product suppliers or marketers.
Children's privacy
The website and app are intended for adults and are not directed to children under 13. Jevumi does not knowingly ask children to provide personal information through the current website or app.
Changes to this policy
Jevumi may update this policy when its website, app, service providers, or data practices change. The Last updated date above identifies the current version. Material new collection should be described before it begins.
