- Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 — General Data Protection Regulation.
- "ECL"
- Act of July 12, 2024 — Electronic Communications Law, regulating, among others, the rules for the use of cookies.
3. Scope of Collected Personal Data
3.1 Data provided directly by the User
When using the Service and Application, we may collect the following personal data provided voluntarily by the User:
- name and surname;
- e-mail address;
- company name / organization;
- invoicing details for services we invoice ourselves (invoices for subscriptions paid through Link are issued by Link);
- content of messages sent via contact forms;
- data given in an Order — described in section 3.4.
3.2 Data collected automatically
When using the Service, the following information may be collected automatically:
- IP address;
- web browser type and version;
- operating system;
- screen resolution;
- device information (type, model);
- date, time and duration of the visit;
- pages visited on the Service and their order;
- source of entry (referring site address);
- data from cookies and similar technologies;
- a hash of the IP address of the person submitting the order form. We compute it with an HMAC function and a secret key; the IP address itself is not stored. The hash is still personal data, because with the key it can be checked against a given address.
3.3 Data in the Application: self-hosted and NetSendo Cloud
NetSendo runs in one of two models.
Self-hosted. The customer installs NetSendo on infrastructure it controls. We have no access to the data processed in such an installation. The customer is the controller of that data.
NetSendo Cloud. We install and run NetSendo for the customer on servers of our subcontractor, Aderlo Cloud (ADERLO PSA), in a data centre in Falkenstein, Germany. We process the data in the customer's instance, such as subscriber lists, campaigns, statistics and phone numbers for SMS, as a processor, only on the customer's instructions, under a data processing agreement (Article 28 GDPR). The customer is the controller of that data. If you are a subscriber to a list run in NetSendo Cloud and want to exercise your rights, please contact the company that runs the list. If you write to us, we will forward your request to that company.
3.4 Order and licence data
For an Order we process:
- order form data: email address, chosen plan, website language, the instance name for NetSendo Cloud, and confirmation of the documents accepted and statements made, with the date and document version;
- data Link passes to us about the transaction: customer and subscription identifiers, payment status and billing period dates, and in the Stripe dashboard also the name or company name, billing address, country, VAT number (if given), card brand and its last four digits. We do not receive full card details;
- licence data: licence key, plan, email address, key expiry and status, and for NetSendo Cloud the instance address;
- licence check data: when a NetSendo installation checks its key, our licence server receives the licence key, the domain under which the installation's panel runs and the NetSendo version; when an installation asks for the free SILVER licence, also the email address and the chosen package. The licence server also sees the IP address of the server the installation runs on;
- correspondence about the Order, including complaints, withdrawal statements and data export requests.
4. Purposes and Legal Basis for Data Processing
Users' personal data is processed based on the following purposes and legal bases:
| Purpose of Processing | Legal Basis (GDPR) |
|---|---|
| Concluding and performing the subscription contract: handling the Order, issuing the licence key, starting and running the NetSendo Cloud instance, transactional emails | Art. 6(1)(b) |
| Handling inquiries and correspondence sent electronically | Art. 6(1)(f) |
| Fulfillment of tax and accounting obligations (issuing invoices, keeping books) | Art. 6(1)(c) |
| Direct marketing of the Administrator's own products and services | Art. 6(1)(f) |
| Sending newsletter and marketing communication | Art. 6(1)(a) |
| Statistical analysis and optimization of the Service | Art. 6(1)(f) |
| Ensuring the security of the Service and protection against abuse | Art. 6(1)(f) |
| Establishment, pursuit or defense against claims | Art. 6(1)(f) |
| Verifying licence keys and preventing their unauthorised use | Art. 6(1)(b); for abuse prevention Art. 6(1)(f) |
| Limiting order attempts from one IP address (protecting the form against abuse) | Art. 6(1)(f) |
| Handling complaints, withdrawals and refunds | Art. 6(1)(b) and (c) |
| Keeping accounting records and tax documentation for sales through Link | Art. 6(1)(c) |
| Keeping evidence of documents accepted and statements made with the Order | Art. 6(1)(c) and (f) |
| Processing data in NetSendo Cloud instances on the customer's behalf | Data processing agreement (Art. 28 GDPR); the legal basis is determined by the customer as controller |
| Informing the people to whose email address a NetSendo licence was issued about new versions of the software, security fixes and changes that need action when updating (email address from the licence, domain and version of the installation); objection at any time through the link in every message or at contact@netsendo.com | Art. 6(1)(f) |
In the case where the basis for processing is the legitimate interest of the Administrator (Art. 6 sec. 1 lit. f GDPR), this interest is in particular: conducting ongoing correspondence, ensuring the security of IT systems, conducting statistical analyses and marketing own products and services. When limiting order attempts, our interest is protecting the order form against automated attempts and payment fraud.
5. Recipients of Personal Data
Users' personal data may be transferred to the following categories of recipients, solely to the extent necessary to achieve the indicated processing purposes:
- IT infrastructure providers — companies that process data on our behalf: Vercel Inc. (USA; website hosting, including the order form and payment notifications, and server logs), Supabase Inc. (order and licence database in the EU region, Frankfurt), ADERLO PSA (Aderlo Cloud; the mail server from which we send transactional emails and messages about new NetSendo versions from noreply@netsendo.com, and the NetSendo Cloud servers), and the Google Cloud infrastructure provider (Frankfurt region, Germany), where our licence server runs;
- Link and Stripe — payment is accepted by Link (Sold through Link, LLC) as merchant of record and processed by Stripe group companies. We pass Link the email address and Order data needed for the payment. Link and Stripe process data for payment, tax, fraud prevention, dispute handling, transaction support and Link accounts as separate controllers, under their privacy policies (link.com/privacy, stripe.com/privacy). To the extent Stripe stores transaction data in our Stripe account for our purposes, it does so under our agreement with Stripe;
- Analytics tool providers — entities providing tools for analyzing website traffic (if used);
- Accounting office and legal advisors — entities providing accounting, tax and legal services to the Administrator;
- Public authorities — in cases provided for by applicable law (e.g., tax offices, courts, law enforcement agencies);
- NetSendo Cloud subcontractor — ADERLO PSA and, through it, Hetzner Online GmbH (data centre in Falkenstein, Germany) as sub-processors of data in NetSendo Cloud instances;
- Providers chosen by the NetSendo Cloud customer — email providers, SMS gateways and AI providers that a NetSendo Cloud customer connects to its instance. The customer chooses and contracts with them itself; the instance sends them data on its instruction.
Companies processing data on our behalf do so under data processing agreements (Article 28 GDPR). Link and Stripe are not our processors to the extent they act as separate controllers.
6. Data Transfer to Third Countries
Personal data may be transferred to the United States in the following cases:
- Vercel Inc. hosts the Website. Website functions, including the order form and payment notifications, run in a Vercel region in the US (Washington, D.C.). Order form data (email address, plan, instance name) and the IP address from which we compute the hash are therefore processed in the US; the same applies to server logs, including visitors' IP addresses;
- Link (Sold through Link, LLC) is based in the US; we pass it the data needed for payment when redirecting to the payment page;
- Supabase Inc. stores the order and licence database in the EU region (Frankfurt); as a US company it may access it remotely to maintain the service;
- the licence server runs on Google Cloud infrastructure in Frankfurt, Germany; the provider belongs to a US-based group and may access the data remotely to maintain the service.
Data in NetSendo Cloud instances is not transferred outside the EEA.
In such a case, the transfer of data takes place on the basis of:
- a decision of the European Commission finding an adequate level of data protection in a third country (Art. 45 GDPR);
- standard contractual clauses (SCC) adopted by the European Commission (Art. 46 sec. 2 lit. c GDPR);
- binding corporate rules (BCR) approved by the competent supervisory authority (Art. 47 GDPR);
- other mechanisms provided for in Chapter V of the GDPR.
Transfers to the US are based on Commission Implementing Decision (EU) 2023/1795 of 10 July 2023 on the EU-US Data Privacy Framework for certified recipients, and otherwise on standard contractual clauses adopted by the European Commission.
The User has the right to obtain a copy of the safeguards used by contacting the Administrator at: contact@netsendo.com.
7. Personal Data Retention Period
Personal data is stored for the period necessary to achieve the purposes for which it was collected, taking into account applicable laws:
| Data Category | Retention Period |
|---|---|
| Paid Orders and subscription data | For the term of the contract and then until the end of the calendar year in which 6 years have passed since it ended (limitation of claims) |
| Accounting and tax data (invoices) | 5 years from the end of the tax year in which the tax obligation arose. This also applies to settlement reports from Link that are NETSENDO accounting records: 5 years from the start of the year following the financial year they concern. |
| Data from e-mail correspondence | Until the correspondence ends plus the limitation period for claims |
| Data processed based on consent | Until the User withdraws consent |
| Data from cookies | According to cookie parameters — maximum up to 13 months |
| Server logs | Up to 12 months for security and diagnostic purposes |
| Unpaid Orders (abandoned payments) | 30 days from starting the order, then deleted |
| HMAC hash of the IP address from the order form | 30 days from submitting the form, then removed from the order; the attempt counter is deleted one hour after its 10-minute window ends |
| Licence keys and their history | For the term of the subscription and afterwards as in the row "Paid Orders and subscription data"; the key is switched off when the subscription ends (GOLD: 7 days after the end of the paid period) |
| Payment event log (Stripe event IDs and types) | 13 months from receiving the event |
| Evidence of documents accepted and statements made with the Order | As in the row "Paid Orders and subscription data" |
| Data in a NetSendo Cloud instance | For the term of the service and 90 days after it ends (instance dormancy: the customer can resume it or request an export), then the instance is deleted; backups expire within a further 2 days, because only the two most recent daily backups are kept. The customer may ask for earlier deletion |
| Licence server call records (content of key checks and SILVER licence requests) | 30 days from the call; key status and date of last check as in the row "Licence keys and their history" |
| History of the messages about new versions (email address, domain and version of the installation, type and date of the message) and the list of people who unsubscribed from them | History: 12 months from sending; the address of a person who unsubscribed, for as long as needed so that they get no more of these messages |
After the indicated periods expire, personal data is deleted or effectively anonymized.
8. Rights of Data Subjects

- Right of access to data (Art. 15 GDPR) — the right to obtain confirmation as to whether personal data is being processed, and to obtain a copy of the data.
- Right to rectification of data (Art. 16 GDPR) — the right to request correction of incorrect or completion of incomplete data.

Personal Data Protection Office
ul. Stawki 2, 00-193 Warsaw

9. Cookies and Similar Technologies
9.1 What are cookies?
Cookies are small text files saved on the User's end device (computer, tablet, smartphone) by the web browser when using the Service. Cookies may be sent by the Administrator's server or by the servers of third parties whose services the Administrator uses. Link's payment page runs on a Stripe domain and uses its own cookies under Link's and Stripe's policies.
9.2 Types of cookies
| Type | Purpose | Consent required |
|---|---|---|
| Essential (technical) | Ensuring proper functioning of the Service, maintaining session, security | No — exempt from the obligation to obtain consent |
| Preferences | Remembering User choices (e.g., language, color theme) | Yes |
| Analytical / statistical | Analysis of how the Service is used, content optimization | Yes |
| Marketing | Displaying personalized content and ads | Yes |
9.3 Cookie management
In accordance with the Telecommunications Law and guidelines of the President of UODO, the User may at any time:
- accept or reject individual categories of cookies via the cookie banner displayed during the first visit to the Service;
- change cookie settings at any time — the management option is available in the footer of the Service;
- manage cookies in web browser settings, including deleting saved cookies.
Refusal to consent to analytical and marketing cookies does not affect the ability to use the basic functions of the Service. Disabling essential cookies may limit the functionality of the Service.
9.4 Rules regarding consent for cookies
When collecting consent for cookies, the Administrator applies the following rules:
- The User has the same easy ability to reject cookies as to accept them;
- analytical and marketing cookies are not activated without the User's prior, express consent;
- consent is voluntary, specific, informed and unambiguous;
- The User may withdraw their consent at any time — the withdrawal procedure is as simple as its granting;
- The Administrator stores proof of consent (date, time, content of the message).
10. Profiling and Automated Decision Making
The Administrator does not make decisions towards Users based solely on automated data processing, including profiling, which would produce legal effects towards them or similarly significantly affect their situation (Art. 22 GDPR).
Basic analytical mechanisms may be used within the Service to optimize content and match communication to User preferences. Such activities do not constitute profiling within the meaning of Art. 22 GDPR, as they do not lead to automated decisions having a significant impact on the User.
In the event of implementing profiling mechanisms or automated decision-making in the future, the Administrator will update this Privacy Policy and inform Users in an appropriate manner.
11. Security of Personal Data
The Administrator applies appropriate technical and organizational measures ensuring protection of processed personal data, in particular securing data against unauthorized access, change, loss, damage or destruction (Art. 32 GDPR).
The security measures used include in particular:
- Data transmission encryption — communication between the User's browser and the Service server takes place using the SSL/TLS protocol (HTTPS certificate);
- Access control — access to personal data is granted only to authorized persons, based on individual permissions;
- Regular backups — Website and NetSendo Cloud data is backed up; NetSendo Cloud instances are copied once a day, encrypted, to a separate server in the EU, and the two most recent copies are kept;
- Software updates — regular updating of systems and software to eliminate known vulnerabilities;
- Personnel training — persons having access to personal data are trained in personal data protection and obliged to maintain confidentiality.
12. Use of Artificial Intelligence (AI)
The NetSendo application offers features based on artificial intelligence, including generating email content, suggesting message topics and planning campaigns using the Campaign Architect module.
In this context, we inform that:
- AI models are provided by third parties — The User configures the integration with a chosen AI provider (e.g. OpenAI, Anthropic, Google) and provides its own API key. In a self-hosted installation requests go from the User's infrastructure, and in NetSendo Cloud from its instance, directly to the chosen provider. NETSENDO PSA does not use these requests for its own purposes.
- Where AI data is processed — in the self-hosted version AI data is processed on the User's infrastructure; in NetSendo Cloud in its instance, under the data processing agreement.
- No automated decision making — AI functions are solely supportive and suggestive. The final decision on the content and sending of the message always belongs to the User;
- AI regulation — we follow rules on artificial intelligence, including Regulation (EU) 2024/1689 (AI Act), and adapt NetSendo's AI features to them.
13. Changes to the Privacy Policy
The Administrator reserves the right to introduce changes to this Privacy Policy in order to adapt it to the current legal state, technological changes or modifications to the scope of services provided.
Users will be informed about any significant changes by:
- publishing the updated version of the Privacy Policy on the Service website;
- updating the "Last updated" date visible at the beginning of the document;
- in the case of significant changes — notifying by e-mail (if the Administrator has the User's e-mail address).
Continued use of the Service after the publication of the updated Privacy Policy means becoming acquainted with its content. However, this does not mean consent to data processing for new purposes — in such cases, the Administrator will ask for appropriate consent from the User.
14. Additional Information — Obligation to Provide Data
Providing personal data by the User is voluntary, however:
- In the case of concluding a contract — giving an email address and, for NetSendo Cloud, an instance name is required to place an Order. You give payment details and the billing address to Link; without them payment is not possible.
- In the case of a legal obligation — providing data for tax and accounting purposes (e.g., on an invoice) results from applicable laws and cannot be omitted.
- In other cases — providing data is fully voluntary and does not give rise to any negative consequences other than the inability to use specific functions of the Service (e.g., contact form, newsletter).
