SinScroll
Privacy Policy
This policy explains information handled by SinScroll, the BlackTzel website and support, and the separate processing performed by the services you choose to use.
Effective date:
About SinScroll and this policy
SinScroll is operated by Jonathan Gabriel Maya, an individual based in Philadelphia, United States, under the BlackTzel brand (“BlackTzel,” “we” or “us”). We are responsible for the information handling described in this policy that we control. Contact us at blacktzel@gmail.com. SinScroll does not create or maintain its own user accounts.
Local app information and information sent to third-party services have different storage and deletion controls. Browsing social websites is online activity, even when app settings are stored on your device.
Preferences and onboarding
SinScroll stores your language choice, onboarding completion, filter settings and onboarding answers on your device. Answers include your selected age, estimated daily scrolling time, goal, reason for using the app and previous attempts to reduce scrolling. They personalize the introduction and time illustrations; they are not medical assessments.
The app does not send these answers or its local browser-time totals to a BlackTzel server. It has no separate developer-operated account or synchronization service.
Instagram sessions and account labels
Each saved Instagram session has a local identifier, display order, sign-in status and, when detected from your own profile navigation, a username used as its label. SinScroll reads authentication cookies to choose an appropriate Instagram starting page.
Each Instagram session uses its own persistent WebKit website data store. YouTube uses a separate persistent store. This separates local cookies and website storage between those sessions; it does not prevent a platform from recognizing your activity through its own accounts, network requests or other signals.
The app does not maintain a separate password database or send your social credentials to BlackTzel. Login forms and verification steps belong to the third-party websites.
Website cookies, browsing and third-party processing
Instagram and YouTube receive requests from the embedded browser. Their services may process your IP address, device and browser information, cookies, sign-in details, searches, viewed content and interactions according to their own policies. Information you type into those websites is sent to their services.
WebKit can retain cookies, local website storage, caches and other website data on your device so sign-in and browsing work between visits. SinScroll’s filters inspect or change parts of displayed pages and navigation locally. Hiding an element does not guarantee that its network request, advertising or tracking has been blocked.
Meta, Google and Apple operate their own services. Their privacy policies and account controls apply to their processing; BlackTzel cannot delete information from those services through a local session reset.
Browser statistics and session timers
SinScroll records foreground time in its social browser as daily totals by platform, for daily and weekly statistics. These totals do not measure your entire device usage. The usage record contains the day, platform and elapsed seconds, rather than a browsing-history list or message contents.
Normal usage entries older than approximately 90 days are removed when new usage is saved. This cleanup does not run as a daily deletion service while the app is unused. Instagram timer and reminder settings are saved locally; the active countdown is held in memory and is not a permanent session-by-session history.
Apple Screen Time permissions
If you grant Family Controls authorization, SinScroll can apply a shield to the native applications you select. Apple’s picker supplies opaque application-selection tokens. The app stores those selections and protection settings locally in a shared container used by SinScroll and its protection extensions. This does not give BlackTzel a remote list of your installed apps or your Screen Time history.
You can turn off a platform’s protection in SinScroll and revoke authorization in iOS Screen Time settings. Revocation stops authorized protection and invalidates saved selections when the app observes the change. Browsing and filtering do not require this optional permission.
Apple purchases
If Pro subscriptions become available, Apple handles checkout and payment information. SinScroll uses StoreKit product information and verified transaction and renewal information, including purchase identifiers, status and expiration, to determine Pro access and restore purchases. Your card details are not supplied to BlackTzel by this app.
The planned subscription system does not send a purchase history to a BlackTzel backend. Apple processes purchase information under its own terms and privacy policy. No public purchase availability or price is established by this policy.
Support email and this website
If you email blacktzel@gmail.com, Jonathan Gabriel Maya receives your email address, message and any attachments you choose to send. Only Jonathan Gabriel Maya has access to the support mailbox; Google processes the email to provide Gmail. The information is used to respond, investigate the issue and handle your request. Do not send passwords, login codes, session cookies, private session tokens or unredacted private messages.
Hostinger provides hosting and content delivery for this website. Website requests send technical information, including an IP address and the requested resource, to that infrastructure. Hostinger may process access logs, traffic reports, security records and backups under its service settings and policies. These SinScroll pages do not set browser cookies or use browser storage, tracking scripts, client-side analytics or remote fonts.
Contact us about information retained in support correspondence or website logs. The app does not provide BlackTzel with remote access to your local preferences, sessions or usage totals.
Where information goes
The app does not send its saved onboarding answers, session catalog or browser-time totals to BlackTzel or an advertising partner. The website has no advertising integration or client-side analytics; Hostinger can produce server-side traffic information from website requests.
Online browsing sends information to the Instagram, YouTube and related web services you use. Apple processes permissions, purchases and relevant system services. Support messages pass through Google’s email service, and website requests reach the hosting infrastructure. These processing boundaries are different from local-only app records.
Analytics and diagnostics
SinScroll does not include a third-party analytics, advertising or crash-reporting SDK. It uses Apple system logging for technical events and subscription errors, with private error details marked private. Some debugging logs are limited to development builds.
Apple may process system diagnostics and make crash or diagnostic information available according to your device choices and Apple’s developer services. Third-party websites may run their own analytics. These arrangements are separate from the local SinScroll usage statistics.
Retention, local deletion and backups
Preferences and sign-in data persist between visits until changed, reset, removed or otherwise cleared. In Profile, platform logout clears the corresponding website data; Instagram logout applies to the selected session. In Instagram session management, reset clears a session’s website data and label, while delete removes that saved session when the control is available.
Deleting a SinScroll session does not delete your Instagram or Google account, messages or data held by those providers. It also does not erase all SinScroll preferences, onboarding answers or browser-time totals. Expiration of Pro access does not delete saved sessions or settings; extra sessions remain visible and can be removed.
To recover from damaged local records, the app may retain recovery copies of session metadata, including usernames and identifiers, or usage records. The normal 90-day usage cleanup and individual session deletion do not necessarily erase those recovery copies. There is no single in-app control to erase every category of local data.
Device or iCloud backups may retain app data depending on Apple’s backup settings. Removing the app is not a guarantee that backups, shared-container data or information already held by third parties are erased. Contact support for help with local cleanup and manage backups separately through Apple’s controls.
Support emails do not have an automatic deletion schedule. They remain in the Gmail mailbox until Jonathan Gabriel Maya manually deletes them. You can request deletion of support correspondence by emailing blacktzel@gmail.com. We will review the request and delete information we control as required by applicable law, subject to any lawful retention obligation. Mailbox deletion does not guarantee immediate removal from Google’s backup or security systems.
Website logs and hosting backups follow Hostinger’s service retention and settings. We use Hostinger’s default settings and have not confirmed an exact retention period for every log and backup category. There is no separate SinScroll-controlled automatic deletion period for those records. Contact us about access or deletion; records controlled by Hostinger may remain subject to its security, backup and legal retention processes.
Security and storage boundaries
App preferences are held in the iOS app container, website sessions in WebKit stores and protection selections in the app’s shared container. Device security and access to your phone affect the confidentiality of these records; they are not a promise of additional app-level encryption.
Keep iOS up to date, use a device passcode and protect your accounts. No app, email service or network connection can guarantee absolute security. Separate session storage does not guarantee anonymity or complete tracking prevention.
Your choices and privacy rights
You can change app settings, use YouTube as a guest, clear local website sessions, stop browsing and withdraw Screen Time permission. Use Meta, Google and Apple account controls for their data and permissions.
Depending on applicable law, you may have rights to access, correct, delete or obtain a copy of information, restrict or object to processing, withdraw consent where relevant, or complain to a competent privacy authority. To request help with information held by BlackTzel, email blacktzel@gmail.com with “SinScroll privacy request” and describe the information and request. We may need proportionate information to verify the request; never send social account credentials.
BlackTzel can address information it holds, such as support correspondence, but cannot retrieve on-device records through a server or delete a third-party account for you. Applicable legal obligations may affect what can be provided or deleted. Service providers may process information outside your country under their own arrangements.
- Sessions: use Profile logout for the active platform session, or reset/delete a saved Instagram session in session management.
- Preferences: the reset control in Instagram settings restores its filter, timer and reminder defaults. Change YouTube options individually. Resetting preferences does not erase usage totals, onboarding answers or website login data.
- Usage records: there is no complete in-app erase control for usage totals or recovery records. Repeating onboarding is not a data reset.
- Permissions: disable protection in SinScroll or withdraw its authorization in iOS Screen Time settings.
- BlackTzel-held information: email a privacy request for support correspondence or other information BlackTzel actually holds.
- Billing: cancel a subscription separately through Apple. A data-deletion request or local session deletion does not cancel it.
Age and children’s privacy
The onboarding age selection starts at 16. It is self-reported and is not age verification or parental consent. Use must also satisfy the age and consent requirements of applicable law and the third-party services involved.
Do not submit children’s personal information in a support request. A parent or guardian with a concern about information sent to BlackTzel can contact us for help.
Policy changes and contact
This policy applies from the effective date shown above. Changes to app features or information handling may require a revised policy. We will show the updated effective date and communicate material changes as required by applicable law.
