DECIDO ("DECIDO", "we", "us", or "our") is a decision-support web application for retail traders. DECIDO does not provide market data, brokerage services, automated trading, or financial advice. It is a personal record-keeping and discipline tool that lets users mark and review their own intentions (GO / WAIT / STOP) per timeframe and per instrument.
This Privacy Policy explains what information we collect, how we use it, who we share it with, and the rights you have. It applies to the DECIDO website and the authenticated DECIDO application.
The data controller responsible for your personal data is:
SalesVoice LLC
Tokyo, Japan

We intentionally collect the minimum data necessary to operate DECIDO.
When you create an account we collect your email address and a username. We do not require your real name. Authentication is operated through Supabase Auth (see Section 4).
DECIDO stores the data you create inside the product: the instruments you track, the folders you organize them into, the GO / WAIT / STOP state you assign per timeframe, free-form memos you write, favorite flags, broker labels, and the timestamps of state changes. This data is private to your account and is never made public or shared with other users.
We collect basic interaction events, feature-preference settings, and timestamps to understand how the product is used and to improve it. When you access the service, we automatically receive your IP address, browser type, device information, operating system, and referrer for security, abuse prevention, and troubleshooting.
Paid subscriptions are processed by Paddle.com Market Limited ("Paddle"), which acts as the Merchant of Record (reseller) for DECIDO. Paddle collects your name, billing address, country, tax identifiers (where applicable), and payment instrument data. Paddle shares with us only the limited information we need to operate your subscription (subscription identifier, plan, status, billing period, country, and a Paddle customer identifier). We do not see, store, or process your full payment card numbers. Paddle's privacy notice is available at paddle.com/legal/privacy.
We use strictly necessary cookies and browser storage to keep you signed in, to remember your interface preferences, and to run a minor A/B test on the public landing page (font variant). We do not use third-party advertising cookies and we do not run cross-site tracking on our marketing pages.
We use your information to:
We do not send promotional or marketing emails without your separate consent.
Where the GDPR or comparable laws apply, our legal bases are: (a) performance of the contract with you; (b) our legitimate interests in operating, securing, and improving the service; and (c) compliance with legal obligations.
We share personal data only with the service providers we need in order to run DECIDO. We require each provider to keep your data secure and to use it only for the purposes we instruct.
We do not sell your personal data, and we do not share it with advertising networks or data brokers.
DECIDO is operated from Japan and our service providers may process your data in the United States, the European Economic Area, the United Kingdom, and other jurisdictions. Where personal data is transferred out of the country in which you are located, we rely on appropriate safeguards such as Standard Contractual Clauses or the equivalent contractual protections offered by our providers.
To be explicit:
We use industry-standard security measures to protect your data, including:
No system is 100% secure, but we take reasonable steps to protect your information from unauthorized access, loss, or misuse, and we will notify affected users in line with applicable law in the event of a personal-data breach that creates a material risk.
We retain your account data for as long as your account is active. When you delete your account, we delete your personal data within 30 days, except where retention is required for: (a) outstanding billing or accounting obligations (which Paddle may retain in line with their own retention schedule and applicable tax law), (b) fraud prevention and security investigations, and (c) compliance with legal obligations.
Server logs are retained for a limited period (typically up to 90 days) for security and troubleshooting purposes.
Depending on where you live (including under the GDPR, the UK GDPR, the CCPA/CPRA, and Japan's Act on the Protection of Personal Information), you may have the following rights:
To exercise any of these rights, contact us at the email address below. We will respond within a reasonable timeframe, and within the period required by applicable law. For billing-data requests, you may also contact Paddle directly.
DECIDO is not intended for users under the age of 18 and is not directed at children. We do not knowingly collect personal information from anyone under 18. If we learn that we have collected data from a user under 18, we will delete it promptly. If you believe a child has provided us with personal information, please contact us.
We may update this Privacy Policy from time to time. If we make material changes, we will notify you through the DECIDO website or by email. The "Last updated" date at the top of this page indicates when this policy was last revised.
