Why this document exists
When you use Remitide you give us personal data that is neither yours nor ours: your customers’ names, tax IDs (NIF), email addresses and payment history. Those people have not given us their consent and probably don’t know we exist.
The GDPR (the EU General Data Protection Regulation) governs this situation precisely: you are the controller, because you decide what that data is used for; we are the processor, because we process it on your behalf. Article 28.3 requires the relationship to be governed by a contract with specific content. This is that contract.
You accept this agreement when you create your account, together with the terms of service. It is binding on both parties. If you need a signed copy for your compliance records, ask for one at soporte@remitide.com.
What is processed, and why
- Subject matter. The processing of the personal data needed for you to keep track of your invoices and send payment reminders to your customers.
- Duration. For as long as your account is active. When you close it, the section on returning data applies.
- Nature and purpose. Collection, storage, organisation, consultation, use to create and send payment reminders, receipt of the replies your customers send through the link in the reminders, comparison of your portfolio with official insolvency publications if your plan includes insolvency monitoring, access by your accounting firm (gestoría) if you authorise it, retention as a record of what was sent, and erasure.
- Categories of data subjects. Your customers: individuals, self-employed people, and the contact people at the businesses you invoice.
- Types of data. Identification data (name, company name, tax ID (NIF)), contact data (email address, phone number, postal address) and financial data relating to their business relationship with you (invoices, amounts, due dates, payments, non-payments, notes and communications, including the replies they send through the link in the reminders).
- What is not processed. Special categories of data under Article 9 (health, beliefs, trade union membership and the rest) are neither requested nor needed. Nor is data about criminal offences. Don’t upload it.
Our obligations
As processor, Blixma Capital Group, S.L. undertakes to:
- Process the data only on your instructions. The documented instructions are this agreement and what you set up in the application. The data is not used for any purpose of our own: not for advertising, not for shared statistics and not to train artificial intelligence models.
- Keep it confidential, including after the relationship ends, and ensure that everyone authorised to process it is bound by the same commitment.
- Apply the security measures required by Article 32, which are described below.
- Help you with your customers’ rights. If one of them exercises the right of access, rectification, erasure or objection, the application lets you handle it yourself directly. If the request reaches us, we pass it on to you without delay and don’t answer it on our own initiative.
- Help you comply with Articles 32 to 36: security, breach notification and impact assessments, to the extent of the information available to us.
- Tell you about a breach without undue delay as soon as we become aware of it, with what we know, so that you can meet your 72-hour deadline with the Spanish Data Protection Agency (AEPD).
- Warn you if we believe an instruction of yours is unlawful, instead of silently carrying it out.
- Return or delete the data at the end, as you choose, and delete any copies unless a law requires them to be kept.
- Make available the information needed to demonstrate compliance, and allow audits on the terms set out below.
Your obligations
This agreement has two sides, and yours is the one most providers leave in the small print. As controller, it is up to you to:
- Have a legal basis for processing your customers’ data and for writing to them. Chasing payment of your own invoice normally relies on the performance of your contract with them or on your legitimate interest, but that is for you to assess, as you know the relationship.
- Have informed your customers about the processing of their data, as required by Articles 13 and 14, including the existence of a processor.
- Make sure the data you upload is accurate and up to date. A mistyped email address on a customer record sends a debt reminder to an unrelated third party, and that is a data breach.
- Deal with your customers’ requests about their data and with the replies you receive to reminders.
- Not use the service to chase debts owed to others, or debts assigned to or bought by you.
- Decide the recipients, content, tone and frequency of reminders, including the texts suggested by the AI and any automatic sending you switch on: these are your instructions, and the lawfulness of what is communicated to each person is your responsibility.
Your customers’ replies from the reminder
Each reminder can include a link for your customer to say they have already paid, give a payment date, report a problem or ask for more time. We receive that reply on your behalf: we save it with its date and time alongside the invoice, show it to you and adjust that invoice’s reminders according to the rules described in the application. On that page we tell your customer that you are the controller of their data and that their rights are exercised with you.
Remitide does not make any legal assessment of these replies or give them any effect beyond adjusting the follow-up. If you want to use them as evidence (for example, that your customer acknowledges the debt), that is for you to assess: the person replying does not identify themselves, they only use the link in the reminder. Reviewing them and deciding what to do is up to you. They are kept with the invoice for as long as you keep it in your account.
Insolvency monitoring
If your plan includes it, every day we compare your customers’ company names (and their tax ID, if the publication includes it) with the “Situación concursal” (insolvency status) entries in Spain’s Official Companies Gazette (BORME), which Remitide obtains on its own account from the open data API of the Official State Gazette (BOE). That comparison and the alerts it produces are processing on your behalf, under this agreement, and the alerts form part of your data: they are kept for as long as the customer remains in your account. Entries that don’t match any customer are deleted after 180 days.
A match by company name is only a possible match: confirming it, and with it pausing reminders to that customer, is your decision. The information is for guidance only and does not replace checking the official publication or the advice of your accounting firm or lawyer. Data source: Agencia Estatal Boletín Oficial del Estado (the Spanish Official State Gazette agency).
If you give access to an accounting firm
You can link your account to an accounting firm that uses Remitide. By accepting the link you instruct us to let that firm see a summary of your payments in its dashboard and access your account with the level of access you choose. You remain the controller of your customers’ data and we remain your processor; the firm does not become our customer in respect of that data.
- The accounting firm acts on your behalf, as a person you have authorised. If it processes your customers’ personal data, the relationship between you is that of controller and processor, and the Article 28 GDPR agreement governing it is a matter for the two of you: Remitide is not a party to it.
- What the firm does inside your account (approving reminders, recording payments, changing settings if you give it that access) is done in your name and recorded in your history with the person who did it.
- You can change or remove the access at any time from Settings › Accounting firm. Once removed, the firm can no longer sign in to or see your company from that moment; anything it had already downloaded falls under your relationship with it.
Security measures
What is in place, with specific names instead of generic wording. The full description is on the security page.
- Isolation between customers. Each company is separated by row-level security in the database itself, not just by a filter in the software. Even if a query forgot to filter, the database would not return another company’s rows.
- Encryption. Traffic is always encrypted. Passwords are stored with argon2id and never in plain text. The credentials for your connections and your mail server are encrypted with AES-256-GCM.
- Access control. Sessions that expire, a limit on sign-in attempts, and role-based permissions within your company.
- Traceability. An audit log of who did what and when, and an exact copy of every reminder sent.
- Network and deployment. The database is only reachable from the hosting provider’s private network, over encrypted connections; the application uses a role without administrative privileges, and each company only sees its own data through row-level security policies.
- Recovery. The database is backed up continuously, encrypted, to a separate store in Amsterdam, so it can be restored to a specific point in time.
Other processors
Engaging sub-processors requires them to be identified, authorised and bound by equivalent data protection obligations. This list does not authorise open-ended processing. Providers acting as independent controllers are not sub-processors for those operations.
By accepting this agreement you give us the general written authorisation provided for in Article 28.2 of the GDPR to use the sub-processors in this table. We impose on each of them, by contract, data protection obligations equivalent to those in this document and, if they fail to meet them, we remain liable to you for their actions, as Article 28.4 provides.
When you connect an account of your own (your Gmail, your Outlook or your Stripe account), that provider also processes the data under your own contract with it. Remitide only uses that connection for what you set up, and you can remove it at any time.
| Sub-processor | Purpose | Location |
|---|---|---|
| Railway ↗Railway Corp. | The server that runs the application and the database where invoices, contacts and reminders are stored. | Netherlands (europe-west4 data centre). Encrypted backups in Amsterdam. Railway Corp. is a US company |
| Stripe ↗Stripe Payments Europe, Ltd. | The payment gateway your customer uses to pay the invoice, through your own Stripe account. The money goes to your account, not ours: we never receive or hold it. Stripe also collects the Remitide subscription; card details are handled by Stripe and we never see them. | Ireland and the United States |
| Resend ↗Plus Five Five, Inc. (Resend) | Delivery of platform emails, such as password recovery, welcome messages and subscription confirmations. It is not a fallback for chasing customer invoices: those reminders require each company’s own connected email account. | United States |
| OpenAI ↗OpenAI Ireland Ltd. | The AI provider: it drafts reminders and answers in the assistant. It receives the customer’s name, the invoice number and amount, the notes and the text of the conversation, and nothing else. Data sent through its API is not used to train its models. | Ireland, with processing in the United States by its affiliates |
| Google ↗Google Ireland Ltd. / Google LLC | Sign-in with Google, and sending reminders from the Gmail account the company connects (gmail.send permission). Not used as an AI provider. | European Union and United States |
| Microsoft ↗Microsoft Ireland Operations Ltd. | Sign-in with Microsoft, and sending reminders from the Outlook account the company connects (Microsoft Graph Mail.Send permission). | European Union and United States |
| Anthropic ↗AnthropicNot yet in use | Alternative AI provider for drafting reminders and for the assistant. Only one AI provider is active at a time; it would receive the customer’s name, the invoice number and amount, the notes and the text of the conversation. | United States |
If we are going to add a new one, we will tell you at least thirty days in advance. During that period you can object; if you do and we can’t find an alternative, you can terminate the agreement without penalty and take your data with you.
Transfers outside the European Economic Area
Some providers are established in the United States or may process data there. Railway Corporation, Stripe, LLC, Plus Five Five, Inc. (Resend), Google LLC and Microsoft Corporation are certified under the EU-US Data Privacy Framework, and transfers to them rely on Commission Implementing Decision (EU) 2023/1795. Their data processing agreements also include the standard contractual clauses adopted by the European Commission in 2021. The AI provider is OpenAI Ireland Ltd., which transfers data to its US affiliates under the 2021 standard contractual clauses, as OpenAI is not certified under that Framework; Anthropic, an alternative provider not currently in use, would likewise rely on standard clauses. A copy of these safeguards is available on request from our privacy email address.
No data is transferred to a third country on any instruction other than yours unless EU or Member State law requires it; in that case we would inform you beforehand, unless the law prohibits it.
Audits
You can check that we comply. On reasonable request and with prior notice, we will provide the necessary information and, if needed, the opportunity for an audit (by you or by a third party you appoint who is bound by confidentiality), during business hours and without disrupting the service to other customers.
Unless required by an authority or following a breach affecting your data, on-site audits are limited to one a year, with at least thirty days’ notice, and each party bears its own costs. The documentation and written answers we provide will normally be enough. An audit does not give access to the data of other businesses using Remitide.
At the end
When you close your account, and as you choose, we return the data or delete it. You don’t need to wait for anyone to get it back: in Settings › Data and privacy you can download it at any time.
Copies are deleted too, except anything a legal obligation requires us to keep (mainly documents with accounting or tax effect), which is blocked: it is kept available to public authorities and the courts and not used for anything else, until the limitation period expires.
Liability
Commercial limits do not reduce the rights of data subjects, the powers of the authorities or the liability that applies under the GDPR. Remitide keeps its legal obligations in respect of its sub-processors. Penalties are not automatically passed on to the customer.
Each party is liable for its own obligations. We are liable for damage caused by processing where we have failed to meet the obligations the GDPR specifically places on processors or have acted outside your lawful instructions. You are responsible for the lawfulness of the instructions you give us and for meeting your obligations as controller.
