The rules for using Demetra. By creating an account you agree to them.
Updated 2026-09-11 · Operator: ИП SHARBAN (see Contacts)
Demetra is a trading-journal service: it records, organises and analyses your own trades and backtests. It includes a web app and an optional desktop app that can synchronise closed positions from MetaTrader 5.
Demetra has two editions. Cloud stores the journal on our servers and supports connected analytics, the AI assistant and sharing; it is not zero-knowledge. Private / Local Vault is free during the current request-based early-access stage: the desktop build keeps journal content in local SQLCipher-encrypted databases and does not upload it to Demetra Cloud. The database key is protected for the current Windows user with DPAPI. Local encrypted backup and same-user recovery are included; cloud backup and synchronization are not. See the Privacy Policy for the exact data flow.
Demetra does not provide investment, financial, tax or legal advice. Analytics, statistics and the AI assistant are informational tools computed from your own data — they are not recommendations to buy, sell or hold anything. You alone make your trading decisions and bear their consequences. Trading carries a high risk of loss.
Don't: break the law, attack or overload the service, reverse-engineer or scrape it, resell or sublicense access, upload others' data without a right to, or abuse the AI assistant. We may suspend or delete accounts that violate these terms or create risk for others. Where reasonably possible we warn first and explain what happened; suspension does not by itself erase your data or void a paid period — export stays available, and refunds follow Payment & refunds and the mandatory law.
Cloud is sold as a subscription. New accounts start on a trial; when it ends, journaling locks until a subscription is paid for, and your data is not deleted in the meantime — you can still export it or delete the account.
The price, how payment is taken, when access starts, how renewal is cancelled and how refunds work are all in Payment & refunds, which is a public offer you accept by paying. Card details never reach Demetra's servers — they are entered on the payment provider's page.
Accounts that existed before the paid model was introduced keep the access they had; this section does not create a charge for a period already used.
Private / Local Vault is free during the current early-access stage. Access is issued manually after a request and may be granted for a limited testing period. There is no Private charge or automatic renewal at this stage. When access expires, journaling locks but the local database is not deleted and local backup/export remains available. Any future paid plan will require advance notice, separate pricing/terms and your explicit agreement; it will not create a retroactive charge.
We aim for reliable service but don't guarantee it's always available, error-free, or that data is never lost — keep your own backups/exports. Private users are responsible for protecting and backing up the local database; there is no current Demetra cloud backup for it. We may change or discontinue features and update these terms; material changes will be announced in advance. A change does not take away what a period already paid for materially included — if a paid feature is discontinued mid-period, Payment & refunds applies. Continued use after a change means acceptance.
The service is provided "as is". To the extent allowed by law, Demetra isn't liable for trading losses, lost profits, or indirect/consequential damages arising from use of the service or reliance on its analytics.
Nothing in these terms excludes or limits liability that cannot be excluded under the mandatory law of the Republic of Kazakhstan — including consumer-protection rules — or restricts rights those laws grant you.
Governing law. These terms and your use of Demetra are governed by the law of the Republic of Kazakhstan. If you use Demetra as a consumer, this choice does not deprive you of protections granted by mandatory rules of the law of your habitual residence.
Disputes. Write to us first — see Contacts & owner. A consumer claim receives a reasoned written reply within 10 calendar days, as the consumer-protection law requires. If we cannot resolve it, disputes are settled under the law of the Republic of Kazakhstan by the competent court; nothing here limits a consumer's right to sue where the law allows.
Which document wins. These pages form one set. If they conflict: personal-data matters follow the Privacy Policy and the consent you gave; payment follows Payment & refunds (the public offer); use of the desktop software follows the License (EULA); everything else follows these Terms. Mandatory law prevails over all of them.
