Article 1 (Basic Policy)

Yu Nakamura (sole proprietor, hereinafter "we" or "us") regards the protection of users' personal information as an important responsibility in providing "totonoeai" (hereinafter the "Service"), and handles personal information appropriately in accordance with this Privacy Policy while complying with the Act on the Protection of Personal Information (hereinafter "APPI") and other applicable laws and regulations.

Article 2 (Definition of Personal Information)

"Personal information" in this Privacy Policy means personal information as defined in Article 2, Paragraph 1 of the APPI — that is, information relating to a living individual that can identify a specific individual by name, date of birth, or other description contained in the information (including information that can be easily cross-referenced with other information to identify a specific individual).

Article 3 (Information Collected)

We collect the following information in providing the Service.

3-1 Account Information (Obtained via Google OAuth)

When a user logs in using a Google Account, we obtain the following information from Google.

For use of paid plans (Light / Premium), the following information is processed through Stripe (operated by Stripe Japan K.K.).

Type of Information Content
Credit card information Card number, expiration date, security code (obtained and managed directly by Stripe; not stored on our servers)
Payment history Charge date and time, amount, transaction ID
Billing information Name, address, etc. entered by the user (if provided)

3-4 Uploaded Files (Temporary Processing) and Data Input to AI

Files uploaded by users for conversion processing (documents, images, videos, etc.) are used solely for the purpose of processing and are deleted within a reasonable period after processing is complete (see Article 5). They may be retained for a certain period to the extent operationally necessary for system logs, backups, caches, etc.

[IMPORTANT] When using AI features, the content of input text, audio, video, and documents is transmitted to the servers (located in the United States) of third-party AI service providers such as Anthropic, PBC (Claude API) or OpenAI, LLC (Whisper API, etc.). Before inputting confidential information, personal information, trade secrets, business-critical information, medical or financial information, or any other information that should not be disclosed to third parties into AI features, please carefully review and use these features at your own responsibility.

Users bear sole responsibility for the legality of data they input and for any infringement of third-party rights (including copyright, trademark rights, portrait rights, privacy rights, trade secrets, and other rights). We do not conduct prior review of content input by users. If a claim of rights infringement or similar claim is received from a third party, the user shall resolve it at their own cost and responsibility.

3-5 Tool Usage History

When a logged-in user runs a text-based tool (Markdown editor, AI document formatting, AI meeting notes, diagram generation, URL shortening, etc.), the input text and output result are stored on our servers (AWS RDS, Tokyo region) for 30 days to support re-use and history restoration. Records older than 30 days are deleted automatically. For file-based tools (PDF conversion, OCR, video processing, etc.), the file itself is not retained — only metadata such as filename, run timestamp, and an output preview. Users can delete individual entries at any time from the "History" tab on the account page.

3-6 Error and Monitoring Information (Obtained via Sentry)

To ensure stable operation of the Service, we use the error monitoring tool "Sentry" (Functional Software, Inc. d/b/a Sentry). Error reports including stack traces, browser information, and session IDs at the time of errors are collected.

3-7 Access Analytics Information (Obtained via Google Analytics 4)

To understand access conditions and improve the Service, we use Google Analytics 4 provided by Google LLC. Cookies collect user behavior (page view history, time on site, referral source, device information, and approximate geographic information). Please refer to Google LLC's website for Google Analytics terms of use and privacy policy.

IP addresses are anonymized (anonymize_ip) on the Google Analytics side and are not used to identify individuals.

3-8 Short URL Safety Verification (Google Safe Browsing)

For URLs entered by users in the Service's URL shortening feature, we use the Google Safe Browsing API provided by Google LLC to verify server-side that the URL is not a phishing or malware site. Only the target URL is sent to Google during verification (users' personal information is not sent).
