This Policy adopts privacy by design and explains how SixTree processes your personal data, in accordance with:
Privacy
This Policy applies to the personal data processed by SixTree in its products, Advisory services and digital channels, including:
It does not apply to third-party websites and services reached through links in our channels. We recommend reading those third parties' policies.

Privacy
To make this document easier to understand, we adopt the terms defined in article 5 of the LGPD, summarised below:
Privacy
We only collect the data needed for the purposes of this Policy (principle of necessity, article 6, III).
| How | What |
|---|---|
| When you fill it in | Data you provide in the Diagnostic Brief, in the contact form and when booking a call |
| When you browse the website | IP address, browser, operating system, pages visited and date and time of access, recorded by the hosting infrastructure |
| Through cookies and local storage | Your cookie preference and, with your consent, usage data from Google Analytics (section 5.4) |
| Through technology providers | Data processed by the processors listed in section 8.1 |
The Diagnostic Brief is a free reading of where your organisation stands. When you take it, we process:
The reading is only sent after you confirm your email address. Answers that are never confirmed are deleted (section 10).
We do not ask for sensitive personal data. The questions concern the organisation. If you mention other people's data, such as partners', treat it with the same care you would in a conversation with SixTree.
When you write to SixTree, we process your name, email, phone number, organisation (optional), the subject you choose, which may be the product or service you are interested in, and the message you write.
When you book a call with SixTree, through the calendar on the website or through any other channel, such as email or message, we process your name, email, the agreed date, time and time zone, and whatever you write when booking. The invitation and the call link are sent to your email, with links to this Policy and to the Terms of Use.
Every booked call is transcribed, to keep a record of what was said and to prepare the next steps. By booking, through any channel, you agree to the transcription, under this Policy and the Terms of Use. Audio and video recording only takes place with your agreement, requested at the start of the call; without it, the call is not recorded. You may ask at any time for the transcription and the recording to be deleted (section 12).
For products and services under contract, recording and transcribing the sessions is part of the service provided and is set out in the proposal or contract.
We use two categories. We do not use advertising cookies or cross-site tracking cookies.
| Category | Purpose |
|---|---|
| Strictly necessary | Running the website and recording your choice about cookies, stored in your own browser |
| Analytics (Google Analytics) | Aggregated statistics on website use. They stay switched off until you accept them, through Google Consent Mode |
Two third-party services used at specific points on the website may also store data in your browser, solely so that they work: the booking calendar (Cal.com), when you open it, and the security check on the forms (Cloudflare Turnstile). Neither is used for advertising.
You can change your choice at any time under Cookie preferences, in the website footer. The list of cookies, with name, purpose and duration, is available on request from office@sixtree.co.
Privacy
| Purpose | Data involved |
|---|---|
| Sending the Diagnostic Brief reading | Registration details, answers and result |

| Booking and holding calls | Booking data (section 5.3) |
| Recording what was discussed and preparing the next steps | Transcription of the booked call and, with your agreement, recording (section 5.3) |
| Providing the products and services under contract | Recording and transcription of the sessions, as set out in the proposal or contract (section 5.3) |
| Managing the business relationship and performing contracts | Registration details and contract data |
| Keeping a history of interactions, so you do not have to repeat information | Registration details, answers and previous contacts |
| Improving the methodology and the questionnaire | Answers and response times, in aggregated and anonymised analysis, without individual identification (article 12) |
| Protecting the forms against abuse | IP address, processed transiently and not stored by SixTree, and Cloudflare's security check (section 11) |
| Sending institutional communications | Email, only with your specific consent (opt-in) |
| Complying with legal obligations and exercising rights | The data required in each case |
Privacy
The Diagnostic Brief reading is generated by automated analysis of your answers, according to methodological criteria defined by SixTree. It describes where the organisation stands and has no legal effect on you or on the organisation. You may ask for the reading to be reviewed by a person at SixTree, and the call we offer after the Brief serves exactly that purpose (article 20 of the LGPD).
Privacy
SixTree does not sell, rent or trade your personal data.
They process data on SixTree's behalf, under contract and only for the authorised purposes:
| Processor | Purpose | Where the data is held |
|---|---|---|
| Supabase (Supabase, Inc.) | Database and access accounts for the Diagnostic Brief | Servers in São Paulo, Brazil; company based in the USA |
| Resend (Resend, Inc.) | Sending the confirmation emails, the reading and internal notifications | Sent from Brazil; logs and metadata in the USA |
| Vercel (Vercel, Inc.) | Website hosting and form processing | Processing in São Paulo, Brazil; global delivery network |
| Google Workspace (Google LLC) | SixTree's email inbox, which receives internal notifications and enquiries | USA and other countries |
| Cal.com (Cal.com, Inc.) | Booking calendar for calls | USA |
| Google Calendar and Google Meet (Google LLC) | Invitations and holding the calls, transcription and, where agreed or under contract, recording | USA and other countries |
| Cloudflare Turnstile (Cloudflare, Inc.) | Checking that forms are submitted by a person and not by a bot | Global network; company based in the USA |
| Google Analytics (Google LLC) | Aggregated usage statistics, only with your consent | USA and other countries |
Where necessary to provide the services, lawyers, accountants, auditors and associated consultants may have access to personal data, always under confidentiality.
We share data with the competent authorities when there is a court order, a legitimate administrative request or an investigation into fraud or a threat to security. Whenever the law allows, we will let you know.
Privacy
Some of the processors in section 8.1 are based or keep infrastructure outside Brazil, mainly in the United States. As a result, some of your data is transferred internationally, including the content of the Diagnostic Brief: name, organisation, answers and the reading, which pass through the email services. The same applies to booking data and to the transcription and recording of calls.
These transfers follow Chapter V of the LGPD (articles 33 to 36) and ANPD regulations, based on data protection contractual clauses agreed with each processor, which ensure protection equivalent to or higher than that required in Brazil. The Diagnostic Brief database is held in Brazil.
Privacy
| Data | Period |
|---|---|
| Diagnostic Brief without email confirmation | Deleted within 30 days |
| Confirmed Diagnostic Brief | While the account exists, and for no more than 24 months after the last contact. After that, deleted or anonymised |
| Enquiries and requests to engage our services that are not taken further | 12 months after the last contact; we send a notice beforehand, and if there is no reply within 30 days the data is deleted or anonymised |
| Clients | For the duration of the contract and a further 5 years, for tax obligations and defence in any legal action |
| Website access records | For the period required by article 15 of the Brazilian Internet Civil Framework, where applicable |
| Call recordings and transcriptions | Up to 12 months after the call, or for the duration of the contract and the periods in the "Clients" row, when the call leads to an engagement. Deleted earlier on request |
| Diagnostic Brief backups | A daily copy, each kept for 90 days |
At the end of the period, data is securely deleted or anonymised, except in the cases set out in article 16 of the LGPD. When you ask for deletion, we erase the data that identifies you; your answers may remain only as anonymous, aggregated statistics.
Privacy
| Measure | How it works |
|---|---|
| Restricted access | Only authorised SixTree consultants access the answers. The database refuses reads and writes from any access made through the browser; only the server writes and delivers data |
| Authentication | Work accounts with multi-factor authentication; respondent accounts without passwords, through a single-use link sent by email |
| Encryption | In transit (HTTPS/TLS) and at rest, to the providers' standard |
| Backups | Daily export, kept for 90 days, with an automatic alert if the routine fails |
| Protection against abuse | Submission limits per source and per email, a hidden field that filters out bots and Cloudflare's security check, without SixTree storing the IP address |
| Separation of information | Anything for the consultants' internal use is never sent to the respondent |
| Contracts | Data protection clauses with each processor |
No system is immune to incidents. If you suspect an incident involving your data, write to office@sixtree.co. If an incident poses a relevant risk or causes relevant harm, we will notify the ANPD and the affected data subjects within the periods set out in article 48 of the LGPD.
Privacy
Under article 18 of the LGPD, you may request at any time: confirmation that we process your data; access to it; correction; anonymisation, blocking or deletion of unnecessary data or data processed in breach of the law; portability; deletion of data processed on the basis of consent; information about who we share it with; information about the possibility of not giving consent and its consequences; objection to processing based on legitimate interest; withdrawal of consent; and review, by a person, of the automatically generated reading (section 7.1).
Write to office@sixtree.co with the subject line "Data Subject Rights · LGPD". We reply within 15 days. Complex requests may need longer, which we will justify. We may ask for information to confirm your identity before dealing with your request.
Privacy
Our services are intended for people aged 18 or over in a professional context. We do not knowingly collect data from children or adolescents (article 14). If we identify inadvertent collection, we will delete the data.
Privacy
If you consider that your request has not been met or that the LGPD has been breached, you may lodge a complaint with the National Data Protection Authority at www.gov.br/anpd.
Privacy
This Policy may change to reflect new practices, laws or technologies. When a change is significant, we will notify by email anyone with an active registration and update the date at the top. Previous versions are available on request. The version accepted by Diagnostic Brief respondents is recorded alongside their answers.
