プライバシーポリシー

収集するデータ

サービスの正常な稼働と検索精度の向上を目的として、以下の匿名運用指標のみを記録します：

• Whether an audio match succeeded or failed
• Whether the vocal separation model was used
• Number of segment rescans requested per session
• Anonymous user thumbs up or down feedback
• Job execution timestamp and processing duration
• Coarse location (country and city derived from Cloudflare request headers)
• Browser language (from HTTP Accept-Language header)
• Coarse device/browser classification (e.g. desktop Chrome, mobile Safari, without raw User-Agent strings)
• Video title of submitted public links for platform extraction and diagnostic quality

収集しないデータ

• No Raw IP Logging: Raw IP addresses are held strictly in temporary server memory for up to 1 hour to enforce rate limits (5 searches/hour), then automatically discarded. Search telemetry records zero raw IP addresses, storing only an ephemeral one-way hashed session ID with a daily-rotating salt.
• Telemetry Retention: Submitted video links and matched song titles are retained in operational telemetry for 90 days solely for system diagnostics and platform extraction reliability, after which they are permanently deleted.
• Automatic File Deletion: Uploaded media and temporary audio slices are purged from temporary storage (in memory when available, otherwise on disk), deleted within 30 minutes
• アカウント不要：会員登録は不要で、当サイト自身によるクロスサイトトラッキングは行いません。ただし、Googleなどの第三者広告パートナーは後述の通りCookieを使用する場合があります。

Cookies & Tracking Technologies

User Rights (GDPR & CCPA/CPRA)

Depending on your jurisdiction, you may possess legal rights regarding your personal data, including the right to request access, rectification, erasure, or opt-out of personal data sharing. Because BGM Finder operates on an ephemeral, accountless architecture, we do not build personal user profiles, sell personal information, or retain persistent personal identifiers.

What We Store

To ensure complete transparency, here is an exact accounting of every data artifact retained across our systems:

• Identified Tracks Catalog (/discover): We store verified song metadata (track title, artist name, album, album art URL, identification count, and discovery timestamp) in a local SQLite database (identified_tracks.db) to power programmatic discovery pages. This database stores zero user identifiers, uploaded files, or IP addresses.
• Share Links (/s/{slug}): Short share URLs smoothly route visitors to public track discovery pages via edge redirects. Short links do not store or transmit user personal data.
• Outbound Click Beacon (/go/{platform}): When you click outbound streaming buttons (Spotify, Apple Music, YouTube), an anonymous click record logs the timestamp, target platform, and search query to evaluate link effectiveness. User IP addresses are never recorded in click logs.
• Aggregated Daily Statistics: Our background analytics aggregate daily query counts, successful match counts, AI separation volume, and error rates in cache.db to monitor infrastructure health. These records contain solely aggregate numbers without individual user profiles.
• Search Telemetry & Operational Logs (usage.jsonl): Submitted media links and successfully matched song titles are logged alongside a daily-rotating hashed session ID to monitor extraction reliability, identify failing platforms, and debug recognition accuracy. Zero client IP addresses are ever written to disk or stored in telemetry logs. Raw search telemetry rows are retained for 90 days and then automatically deleted.
