A STARK-Up Initiative

Your privacy deserves clear answers.

Jouhatsu is a STARK-Up Initiative, initiated and operated by STARK-Up GmbH. Access is currently limited to invited accounts. Here is how to use the service, manage your information and find the right support.

Your control, step by step

Support first. Use specialist reporting routes without entering a case. They are independent external services.
Adult self-help workspace. The current safety agreement is self-attestation, expires after 90 days and proves neither identity nor account ownership. Child and representative intake remains closed.
Independent sign-in. The self-hosted workspace uses Supabase Auth for email codes and, where enabled, Google sign-in. Jouhatsu uses essential HttpOnly session cookies. Your email and sign-in activity are processed by the identity provider; case records remain separate. Email verification does not establish external account ownership.
Separate approvals. Choose whether to send a message to AI, search an identifier or store a link. Local reporting plans do not fetch the target page or send a report.
Minimal records. Inventory stores URLs, labels, platform and progress. Cases store URLs, country, incident category and progress. Safety agreements store role, version and acceptance time.
AI and search. Jouhatsu uses an external AI provider to process approved messages and search identifiers. Official-guide queries include the selected platform. Chat remains in the current tab, but provider processing can involve logs and retention. Jouhatsu does not promise zero retention by its service providers.
Export and erase. Workspace controls export records or delete inventory, cases, the safety agreement and your partnership enquiries. Daily quota counters remain until pruned on subsequent AI use. External service records and provider backups are unaffected.
No publicity by default. Free assistance is separate from campaign stories. No paid victim packages, advertising in the case workspace or sale of case data. Organisational training, implementation and funding arrangements are separate and require reviewed agreements.
Human decisions. AI provides general procedural information and can be wrong. Hosts decide removal; legal assessments belong with qualified professionals. No automatic deletion, face search or background radar is active.

Keep your protection desk private

Save an encrypted recovery file before leaving, and keep its passphrase safe. Local records are separate from your saved workspace cases.

Local processing, recovery and reminders

The protection desk processes eligible adult files locally using SHA-256, without uploading bytes, filenames or hashes. It has no face recognition, image preview or AI processing. Records live in tab memory until cleared or the page closes. Optional passphrase-encrypted recovery files preserve the action queue, fingerprints and report log together; encryption and unlocking happen on the user’s device. Jouhatsu receives no record or passphrase and cannot reset it. Legacy unencrypted exports remain available and are labelled sensitive. No cloud backup or autosave runs. Browser memory erasure cannot be guaranteed. These local records are separate from database export and deletion below. Follow-up calendars omit URLs and report references; importing them into another provider follows that provider’s terms. No external blocking network receives these hashes. No reports, searches or background checks run automatically.

About activity figures

How figures are counted

Page views count signed-in page loads, including reloads. They do not represent unique people. The page-view counter stores a date and aggregate total, without analytics cookies, IP addresses or user identifiers in the counter.

Cards appear only when their recorded count is at least 10. Smaller categories are omitted, and outcome figures are rounded down to groups of five.

Cases and actions describe current saved records; updating or deleting records changes the totals. Removal outcomes are reported by users and are not independently verified. They are not lifetime totals or proof that Jouhatsu caused a removal. The public-facing figures expose no case names, URLs or country breakdowns.

Your records. Your choice.

You must be signed in to your workspace. Export and erasure are available even when your safety agreement has expired. Erasure affects Jouhatsu records only.

Using Jouhatsu, step by step

Find possible accounts

Add account or content links to your protection desk. Review the prepared drafts and official reporting routes, then submit through the relevant service.

Find support and reporting routes

What to expect from each request

Ownership checks happen with the platform. Complete its identity and account checks directly. Jouhatsu’s adult self-help agreement is self-attestation, not identity verification.
You approve and submit. Preparing a draft or opening guidance does not send a report. Record a submission after completing the official process, and keep the platform’s acknowledgement.
Source and search are separate. Removing a search result does not remove the original page. Track each request and response separately.
Choose when to follow up. Set a date in your protection desk or export a calendar reminder. Jouhatsu does not run background monitoring or automatically remove accounts or content.
Save before leaving. Download an encrypted recovery file to return to your local protection desk later. It is separate from saved workspace cases.
Guided tools remain available. If Yonigeya cannot respond, use direct search links, official platform guidance, the protection desk or specialist support.

The signed-in case workspace is for adults acting for themselves. Child and representative case intake is not offered here. For legal advice, contact a qualified professional; in immediate danger, use local emergency services.
