the platform together.
Last updated: May 19, 2026. Version 3.0.
Read before opening an account. No fine print — written to be understood, not to hide information. Version 3.0 reflects the current offering: CHF account with 18.5% APY yield, progressive withdrawal schedule, and optional CDB term deposit.
2. Description of service
BlueLock is a technology (fintech) platform that operates 100% online via Web App (browser) and offers: (a) multi-currency account with CHF balance that yields 18.5% per year (APY) with monthly compounding — see clause 4; (b) progressive withdrawal schedule on yielding CHF — see clause 5; (c) optional CDB BlueLock term deposit (2.1% to 3.2% p.a.) — see clause 6; (d) real Swiss IBAN held by partner bank UBS; (e) real-time BRL ↔ CHF FX; (f) Visa and Mastercard cards (virtual immediately; physical cards unlocked after 12 months of fidelity); (g) SEPA, SWIFT, SIX, and Pix transfers. BlueLock is not a bank. CHF balances are held by the Swiss partner bank, regulated by FINMA. BRL balances are held by the Brazilian partner bank, regulated by BACEN. BlueLock does not offer a native iOS or Android app — the entire service is delivered via a responsive Web App.
3. Eligibility
To open a personal account, you must: (a) be 18 or older; (b) be a Brazilian resident with active CPF; (c) not appear on international sanctions lists; (d) not reside in a sanctioned country (see /aml-kyc/ for list). Refusal does not entitle you to compensation.
4. Yield on CHF balance (18.5% APY)
Free CHF balance (total CHF balance minus active CDB principal — see clause 6) yields 18.5% per year (APY) with monthly compounding. Yield is credited monthly, in CHF, to the free balance itself. Illustrative example: CHF 10,000 held for 12 months generates approximately CHF 1,850 in yield, totaling CHF 11,850. Minimum deposit of CHF 1,000 to open a CHF balance — deposits below this amount are rejected at approval. The 18.5% APY rate is the current nominal rate published at /taxas/; it may be revised with 60 days' prior notice by email + Web App notification. BRL balances do not earn yield under this clause.
5. Progressive withdrawal schedule (saque postupno)
CHF withdrawals are released on a cumulative basis according to time elapsed since the first approved CHF deposit: 1.5% at month 1 · 3.0% at month 2 · 4.5% at month 3 · 9.0% at month 6 · 18.0% at month 12 and thereafter. The released fraction is applied to the free CHF balance at the time of the request. The blocked balance continues to earn APY normally. This schedule exists to stabilize the CHF custody pool at partner bank UBS in line with applicable prudential liquidity rules. Withdrawals requested above the released fraction are rejected as insufficient_unlocked. Credited yield counts as normal free balance and follows the same schedule. Brazilian taxation follows the regressive IOF + IRPF table on foreign-held yield (see clause 9).
6. CDB BlueLock (optional term deposit)
CDB BlueLock is an optional product in which the client locks part of the CHF balance for a fixed term in exchange for a pre-agreed fixed rate (currently 2.1% to 3.2% p.a., simple interest, see /taxas/). Minimum: CHF 500. Features: (a) principal is unavailable for withdrawal until maturity; (b) locked principal does not count as free balance and does not earn the 18.5% APY — only the fixed CDB rate; (c) early redemption is allowed with total loss of accrued yield, principal returned to free balance immediately; (d) at maturity, principal + interest are automatically credited to the free balance, which then starts earning 18.5% APY normally. Clients may hold multiple CDBs simultaneously. The CDB is not covered by Brazil's FGC nor Switzerland's Esisuisse — the product is held by partner bank UBS under the same arrangement as the free balance.
7. Fees and costs
Current fees are always published at /taxas/. Summary: 0.4% transfer, 0.3% FX spread, no monthly fee, no maintenance fee, no opening fee. APY yield credit: free. Fees may change with 30 days' prior notice by email + Web App notification. Operations in progress at the time of the change follow the old fee. Already-contracted CDBs keep their fee from the contracting moment until maturity, even if the table for new contracts changes.
8. Operational limits
Standard personal account: CHF 100,000/month inbound, CHF 100,000/month outbound (subject to the progressive withdrawal schedule in clause 5). Limit increases require Enhanced Due Diligence — proof of fund origin, purpose of movement, fiscal due diligence. Limits may be reviewed unilaterally by BlueLock for regulatory reasons.
9. Client responsibilities
You are responsible for: (a) keeping registration data up to date; (b) protecting password, 2FA, and biometrics against unauthorized access (we recommend updated browser + password manager + mandatory 2FA in the Web App); (c) reporting unauthorized suspicious operations within 60 days; (d) complying with BR fiscal obligations on CHF balance and yield — in particular CBE declaration to the Central Bank when balance exceeds USD 1 million equivalent, and IRPF on foreign-held yield (monthly carnê-leão on credited APY yield, per current Brazilian law); (e) responding to compliance requests within a reasonable timeframe; (f) understanding that CDBs lock principal and that free-balance withdrawals follow the progressive schedule.
10. BlueLock's responsibilities
BlueLock commits to: (a) operating the announced services with reasonable diligence; (b) crediting APY yield monthly on the first business day of each calendar month, with tolerance of up to 3 business days for regulatory windows; (c) processing withdrawal operations within published timeframes (subject to Swiss and Brazilian banking windows); (d) providing support within published SLA; (e) notifying significant changes in advance; (f) reimbursing loss caused by proven technical failure of our platform; (g) maintaining correct and auditable accounting of free balance vs CDB principal.
11. Limitation of liability
BlueLock is not responsible for: (a) favorable or unfavorable BRL ↔ CHF FX movement over time; (b) blocking or delay caused by partner bank, regulator, or force majeure; (c) loss arising from cyberattack on client device or browser when the client is at fault in protection; (d) fiscal consequence of operation that the client voluntarily declared to BlueLock; (e) client impact arising from a revision of the APY rate or the withdrawal schedule, provided the prior notice in clauses 4 and 5 has been respected. The 18.5% APY rate is the current nominal rate, not a perpetual guarantee; it may be revised per clause 4.
12. Web App and supported devices
BlueLock is provided exclusively via Web App on updated browsers — Chrome, Safari, Firefox, and Edge on their two most recent versions. We do not publish native iOS or Android apps; the /app/ path permanently redirects to /web-app/. Features such as Apple Pay and Google Pay are configured via the Web App and add the BlueLock card to the client's native operating system wallet. BlueLock is not responsible for incompatibilities in browsers outside this list or in operating systems unsupported by the manufacturer.
13. Account closure
You may close your account at any time, without penalty, via the Web App or email. On closure: (a) active CDBs are liquidated early with loss of accrued yield, principal returns to free balance; (b) free CHF balance is fully released, disregarding the progressive withdrawal schedule — account closure is a liberating event; (c) balance is converted to BRL at the moment's rate (with 0.3% BlueLock spread) and returned via Pix within 48h. BlueLock may close an account unilaterally in cases foreseen in /aml-kyc/, with email notification; in that case, free balance is fully released, CDBs liquidated with pro rata yield calculated up to the closure date.
14. Jurisdiction and venue
These terms follow Brazilian law for personal individual clients residing in Brazil. Venue: São Paulo — Brazil. For CHF operations held by the Swiss partner bank, Swiss law (LBI, GwG, FinMG) also applies where applicable.
15. Updates
These terms may be revised. Previous versions are archived and available upon request. Significant changes — in particular a revision of the APY rate (clause 4) or the withdrawal schedule (clause 5) — are notified by email + Web App notification 60 days before taking effect. Non-material changes (corrections, wording improvements) take effect with 30 days' notice. Current version: 3.0. Last revision: May 19, 2026.
