License Grant

Lettersiro grants you a limited, non-exclusive, non-transferable, and non-sublicensable right to use the Font Software only within the scope of the license you purchased.

You do not purchase ownership of the Font Software.

All copyright, intellectual-property rights, font-design rights, and other rights in the Font Software remain the exclusive property of Lettersiro.

Your permitted use is determined by:

  • this EULA;
  • the specific license category purchased;
  • the quantity, tier, users, domains, projects, sales volume, impressions, or other limits selected at purchase; and
  • any written Custom or Corporate agreement issued by Lettersiro.

Where a specific purchased license contains more specific usage limits than this general EULA, the specific purchased license terms apply to that usage.

Any rights not expressly granted are reserved by Lettersiro.

2

License Categories

Lettersiro offers nine principal license categories: Desktop, Web Font, E-Pub, Editable Template, Extended & Logo, App/Software/Game, Server, Broadcast & Film, and Corporate.

The specific scope and any quantity or tier selected at purchase determine your rights. Extended & Logo and Corporate include some rights that are otherwise licensed separately. An additional license is required only for uses or quantities not already covered by the purchased package.

2.1

Desktop License

The Desktop License is intended for local installation and ordinary design work. The standard license covers two users and two device installations.

It may be used for:

  • graphics and static designs;
  • documents;
  • posters;
  • flyers;

  • logo concepts and non-trademark logos;
  • flattened or outlined artwork;
  • and other permitted desktop-created designs.

The Desktop License permits End Products for Sale up to 20,000 combined sales/units.

Additional Desktop users increase only the number of people permitted to install and use the Font Software. Additional users do not multiply the 20,000-unit sales limit.

The Desktop License does not permit:

  • trademark registration of a logo;
  • webfont embedding;
  • eBook/ePub embedding;
  • app, software, game, or SaaS embedding;
  • server installation or automated generation;
  • paid digital advertising;
  • POD and template-based uses requiring an Editable Template License;
  • editable templates for resale where font access would be provided;
  • broadcast, television, cinema, OTT, or professional streaming production;
  • AI/ML training or dataset creation;
  • redistribution of Font Software.
2.2

Web Font License

Website embedding requires Web Font coverage, whether purchased as a Web Font License or already included in an applicable Extended & Logo or Corporate package.

Permitted uses may include:

  • @font-face embedding;
  • self-hosting supplied webfont files;
  • website headings;
  • navigation;
  • buttons;
  • landing pages;
  • product pages;
  • blogs;
  • portfolios;
  • e-commerce websites;
  • commercial or personal websites.

Your license must cover the applicable number of websites/domains and traffic/pageview tier purchased.

A Web Font License does not permit:

  • embedding in apps or software;
  • ePub embedding;
  • server-side generation;
  • public font download;
  • user-accessible extraction;
  • public design editors;
  • logo makers;
  • template generators;
  • print customization systems;
  • systems where visitors may type with the font and export their own designs;
  • AI training or dataset creation.

Such interactive or broader uses require another applicable license or a Custom/Corporate agreement.

Extended & Logo includes one website with up to 1,000,000 monthly page views. Corporate includes web use with unlimited monthly page views within the purchased scope. Separate Web Font coverage is not required for the same use when that use is already included in the purchased package.

2.3

E-Pub License

Embedding in an electronic publication requires E-Pub coverage, either purchased separately or included in an applicable Extended & Logo or Corporate package.

This may include:

  • eBooks;
  • ePub files;
  • digital magazines;
  • digital comics;
  • electronic publications.

The Font Software may be used within cover text, titles, headings, body text, or decorative typography according to the number of publication titles covered by the purchased tier.

An E-Pub License does not grant rights for:

  • website embedding;
  • apps or software;
  • games;
  • SaaS;
  • server-generated publications;
  • POD products;
  • unrelated editable templates;
  • redistribution or extraction of the Font Software;
  • AI training.

Extended & Logo includes up to two ePub titles. Corporate includes unlimited ePub titles within the purchased scope. Additional coverage is needed only when the intended use exceeds the included rights.

2.4

Editable Template License

The Editable Template License covers work in editable-template environments such as Canva or Corjl, and the POD or template-based uses stated in the purchased license. It is limited to one official business or brand owned by the Licensee.

Within that licensed brand and the purchased scope, you may:

  • use the template for personal and commercial projects;
  • edit text, colors, images, fonts, and layout;
  • use the edited design in social media, websites, presentations, advertising, and printed materials;
  • create final designs for clients;
  • deliver final, non-editable JPG, PNG, or PDF files to clients;
  • create physical end products using a significantly customized design.

These permissions concern template use and finished design outputs. They do not by themselves grant unrelated website font embedding, app embedding, server installation, trademark registration, or broadcast rights. Those uses require coverage under the applicable license or package.

The one-brand limit is not a blanket permission to use one purchase across several unrelated businesses or brands. Any additional brand coverage or other specific limits must be stated in the purchased terms or a written agreement.

Customers and unlicensed third parties must not be able to download, extract, install, or reuse the original Font Software. Finished or customized products must not expose the font as a reusable font asset.

It is prohibited to sell the Font Software itself, alphabet packs, letter bundles, font packs, individual glyph sets, SVG alphabets, embroidery alphabets, or typeable derivative font products. AI/ML training and dataset use are prohibited unless separately authorized in writing.

2.5

Extended & Logo License

An Extended & Logo License is required when Lettersiro Font Software is used for expanded commercial purposes or to create a logo, wordmark, or brand mark intended for trademark registration or official brand ownership.

This license covers up to 10 users and permits one trademark logo or wordmark.

Permitted:

  • use the Font Software by up to 10 users;
  • create one logo, wordmark, or brand mark;
  • register the final logo, wordmark, or brand mark as a trademark;

  • use the Font Software in YouTube videos;
  • embed the Font Software in up to two ePub titles;
  • use the Font Software for the permitted purposes for a lifetime.

The Extended & Logo License grants trademark rights in the finished logo or wordmark, but does not transfer ownership of the Font Software.

Prohibited:

  • use in broadcast television or film productions;
  • use or embedding in applications, software, games, servers, or cinema productions;
  • redistribute, resell, share, sublicense, or give away the Font Software;
  • transfer the Font Software to a client or any unlicensed third party;
  • modify the Font Software to create a derivative font;
  • upload the Font Software to public servers, template platforms, stock websites, or file-sharing services;
  • use the Font Software for artificial intelligence training, machine-learning datasets, or generative AI systems;
  • use the Font Software beyond the users, logo, products, website, page views, advertising impressions, or ePub limits stated above.

Separate or upgraded licensing may be required for any use that exceeds these limits or is not expressly permitted under the Extended & Logo License.

The website, ePub, and digital-advertising rights listed above are already included in this package. Separate licenses are not required for those same uses while they remain within the stated limits.

2.6

App / Software / Game License

Embedding in an application, software product, game, SaaS product, or interactive digital product requires an App/Software/Game License or a Corporate package that expressly includes the applicable embedding rights.

Permitted uses may include:

  • application interfaces;
  • menus;
  • buttons;
  • splash screens;
  • HUDs;
  • dialogue boxes;
  • onboarding;
  • in-game text;
  • mobile apps;
  • desktop apps;
  • web apps;
  • SaaS interfaces;
  • PC/console/mobile games;
  • Unity, Unreal, Godot, or similar projects.

Each license covers the number of projects included in the purchased tier.

Updates, patches, and minor updates to the same licensed product may be included within the same project.

This license does not allow:

  • use in multiple unrelated products beyond the purchased quantity;
  • Font Software extraction by users;
  • public design editors;
  • public logo makers;
  • user-facing template-generation systems;
  • server-side generation unless separately licensed;
  • website webfont use unless separately licensed;
  • AI training.
2.7

Server License

A Server License is required where the Font Software is installed on or used by a server for automated rendering, processing, or generation.

Examples include:

  • automated PDFs;
  • invoices;
  • reports;
  • certificates;
  • images;
  • previews;
  • mockups;
  • personalized output;
  • print-production workflows;
  • backend rendering systems;
  • internal automated design systems.

The license must cover the applicable number of servers or tier purchased.

A Server License does not allow the server to become a public font distribution system.

End users must not be able to:

  • download;
  • extract;
  • install;
  • copy;
  • directly access

the Font Software.

Public design generators, logo makers, template editors, or similar user-facing customization services require separate written authorization or an appropriate Custom/Corporate license.

A Server License does not automatically grant Web Font, App, Game, ePub, or other unrelated rights.

2.8

Broadcast & Film License

A Broadcast & Film License, or a Corporate package that includes the applicable rights, is required for professional use of the Font Software in:

  • film;
  • cinema;
  • short films;
  • television;
  • documentaries;
  • television commercials;
  • music videos;
  • trailers;
  • opening titles;
  • end credits;
  • lower thirds;
  • broadcast graphics;
  • OTT;
  • professional streaming productions.

The number of productions, territories, audiences, or distribution scope is determined by the purchased tier.

Promotional graphics directly related to the licensed production may be included where stated by the purchased license.

A Broadcast & Film License does not automatically include:

  • trademark logo registration;
  • unrelated paid digital advertising campaigns;
  • app/software/game embedding;
  • website embedding;
  • ePub embedding;
  • server embedding;
  • POD or editable-template resale.

Those uses require the applicable additional license unless included in a written Corporate/Custom agreement.

2.9

Corporate License

The Corporate License covers broader use within the licensed company or organization. The standard published Corporate scope includes:

  • unlimited licensed users;
  • unlimited commercial projects;
  • web use with unlimited monthly page views;
  • unlimited ePub titles;
  • unlimited merchandise sales;
  • digital advertising with unlimited impressions per month;
  • one trademark logo or wordmark;
  • unlimited software, app, and game projects;
  • unlimited broadcast and film use.

These rights remain subject to the purchased plan, the licensed organization, and any written Corporate agreement. Multiple teams, branches, subsidiaries, vendors, internal brand systems, DAM systems, or brand portals are covered only to the extent included in that plan or agreement.

Server installation and public design generators, logo makers, template generators, or user-facing customization services require the applicable Server coverage or specific written authorization. The standard Corporate list does not automatically grant every unlisted use.

Corporate licensing does not transfer ownership of the Font Software. Resale, standalone sublicensing, public font downloads, and competing derivative fonts are prohibited. AI/ML training or dataset use requires express written authorization.

3

Client Work

You may use the Font Software to create permitted work for clients within the scope of your purchased license.

You may provide clients with:

  • flattened JPG/PNG files;
  • PDFs;
  • printed artwork;
  • outlined/vectorized text;
  • final logo artwork;
  • other non-font finished outputs.

Unless expressly permitted under a Corporate or Custom agreement, you may not provide the original Font Software to a client.

If a client needs to install, edit with, or independently use the Font Software, that client must obtain an appropriate Lettersiro license.

A license that expressly grants trademark-logo rights allows delivery of final outlined or static logo artwork to the client, but does not authorize transfer of the Font Software to an unlicensed party.

4

Printers, Manufacturers, Agencies, Contractors, and Service Providers

Providing finished or outlined artwork to a printer, manufacturer, agency, developer, or other service provider is permitted where necessary for a licensed project.

Providing the Font Software itself is not permitted by default.

A third party that needs to install or directly use the Font Software must:

  • hold its own appropriate license; or
  • be specifically covered as an authorized user/vendor under the Licensee’s Corporate or Custom written agreement.

Merchandise manufacturers and printers must not receive the Font Software merely because they are producing licensed goods.

5

Installation and Licensed Users

Only users covered by the purchased license may install or use the Font Software.

Installation on additional computers or by additional people requires additional user coverage unless your license expressly provides otherwise.

A user, seat, device, server, domain, project, campaign, publication, logo, or other licensed quantity cannot be multiplied beyond the purchased limits.

6

Font File Sharing and Redistribution

You may not:

  • sell the Font Software;
  • redistribute it;
  • sublicense it;
  • lend it;
  • rent it;
  • donate it;
  • publish it;
  • upload it for public download;
  • share it with unlicensed coworkers;
  • share it with clients;
  • distribute it in design templates;
  • include it in bundles;
  • provide it as an extractable asset.

Reasonable backup copies may be kept solely for archival/security purposes under the Licensee’s control.

7

Font Modification and Outlines

You may convert text created with the Font Software into:

  • outlines;
  • curves;
  • vector shapes;
  • rasterized graphics.

You may modify those resulting graphic outlines as part of a design project.

However, unless Lettersiro gives prior written permission, you may not:

  • modify the original Font Software;
  • rename it;
  • convert it into another distributable font format;
  • reverse engineer it;
  • decompile it;
  • create a derivative font;
  • recreate a typeface based substantially on the Font Software;
  • redistribute modified font software.
8

Artificial Intelligence and Machine Learning

Except where Lettersiro expressly grants written permission under a Custom or Corporate agreement, the Font Software may not be used for:

  • artificial intelligence training;
  • machine-learning training;
  • dataset creation;
  • typography-generation datasets;
  • font-generation models;
  • model fine-tuning;
  • generative model training;
  • synthetic-font training;
  • or similar computational training purposes.

This restriction applies even if the Font Software is lawfully licensed for another use.

9

Trademark Rights

A Desktop License or other non-Trademark license does not grant trademark-registration rights unless expressly stated.

Trademark authorization must be expressly included in the purchased Extended & Logo License, Corporate License, or written Custom agreement. The standard Extended & Logo and Corporate packages each cover one trademark logo or wordmark.

A trademark license applies to the resulting approved logo/wordmark, not to ownership of the Font Software.

Lettersiro retains all ownership rights in the Font Software itself.

10

End Products and Sales Limits

Where a license includes a sales/unit limit:

  • the limit is cumulative across the licensed use;
  • the limit is not multiplied by users;
  • the limit is not multiplied by computers;
  • the limit is not multiplied by stores;
  • the limit is not multiplied by marketplaces;
  • the limit is not multiplied by products;
  • the limit is not multiplied by clients.

Before exceeding a purchased limit, the Licensee must obtain the required upgrade or additional license.

Desktop permits up to 20,000 combined sales/units. Extended & Logo permits up to 1,000,000 end products for sale. Corporate permits unlimited merchandise sales within the purchased scope. Editable Template use remains subject to its one-brand scope and the applicable purchased terms.

11

License Upgrades and Additional Rights

If your intended use exceeds your existing license, you must obtain the applicable license upgrade, additional license, Corporate plan, or Custom agreement before exceeding the licensed scope.

Purchasing additional Desktop seats increases user coverage only and does not automatically expand other usage limits.

Contact Lettersiro if your usage cannot be clearly covered by an existing license.

12

Free, Demo, and Promotional Fonts

A free, demo, trial, promotional, or limited font is governed by the specific license supplied with that font.

A free/demo download does not automatically include the same rights as a paid commercial license.

Commercial rights must be expressly granted.

13

Ownership

The Font Software is licensed, not sold.

Lettersiro retains all rights, title, ownership, copyright, and intellectual-property rights in the Font Software.

No purchase transfers copyright or ownership of the underlying typeface or Font Software.

14

Prohibited Uses

Unless expressly authorized in writing, you may not:

  • redistribute Font Software;
  • sell Font Software;
  • sublicense Font Software;
  • make Font Software publicly downloadable;
  • create derivative fonts;
  • use Lettersiro letterforms to create a competing font product;
  • remove or obscure ownership information where technically present;
  • use Font Software outside the purchased license scope;
  • use Font Software for AI/ML datasets;
  • knowingly assist another party in violating this EULA.
15

Custom Licensing

Projects that fall outside Lettersiro’s standard licensing may require a Custom License.

Custom terms are valid only when confirmed in writing by Lettersiro.

Where a signed/written Custom agreement conflicts with this standard EULA, the specific Custom agreement controls for the rights expressly granted in that agreement.

16

Term and Duration

Unless a purchased license expressly states otherwise, licenses are granted for the duration specified at purchase.

Where the purchased license states lifetime use, no recurring license fee is required for continued use within the originally purchased scope.

Lifetime usage does not permit usage beyond the purchased limits.

17

Termination for Breach

Your license rights may terminate if you materially violate this EULA or exceed your purchased license rights without authorization.

Upon termination, you must cease new use of the Font Software and remove unauthorized copies.

Lettersiro reserves all remedies available under applicable law for unauthorized use, infringement, redistribution, or other violations.

Nothing in this section limits any mandatory rights or remedies provided by applicable law.

18

Refund Policy

Because Font Software is a digital product, completed purchases are generally non-refundable once access/download has been provided, except where a refund is required by applicable consumer-protection law.

19

Disclaimer of Warranties

The Font Software is provided on an “as is” and “as available” basis to the maximum extent permitted by law.

Lettersiro does not warrant that the Font Software will meet every specific requirement, software environment, workflow, or technical configuration.

The Licensee is responsible for verifying compatibility before relying on the Font Software for a particular project.

Mandatory statutory warranties that cannot legally be excluded remain unaffected.

20

Limitation of Liability

To the maximum extent permitted by applicable law, Lettersiro will not be liable for indirect, incidental, special, consequential, or business-interruption damages arising from use or inability to use the Font Software.

Nothing in this Agreement excludes or limits liability that cannot lawfully be excluded under applicable law.

21

Compliance and Records

The Licensee is responsible for ensuring that its usage remains within the purchased scope.

Where reasonably necessary to investigate an apparent license violation, Lettersiro may request information sufficient to verify applicable license scope, such as:

  • number of users;
  • relevant project;
  • licensed domain;
  • sales tier;
  • app/project count;
  • trademark usage;
  • publication count;
  • or other relevant license dimensions.

Any such request should be proportionate to the suspected usage issue.

22

Amendments

Lettersiro may update this EULA from time to time.

Unless required by law or expressly agreed otherwise, an updated EULA applies to licenses purchased after the effective date of the updated version.

Existing licenses remain governed by the terms applicable to the purchase when made, together with any later written upgrade or amendment accepted by the Licensee.

23

Governing Law and Dispute Resolution

This EULA is governed by the laws of the Republic of Indonesia, without prejudice to mandatory consumer-protection rights that may apply to customers in other jurisdictions.

Subject to applicable mandatory law, disputes arising from this Agreement shall be submitted to the competent courts having jurisdiction over Lettersiro’s principal place of business in Indonesia.

24

Severability

If any provision of this EULA is found invalid or unenforceable, the remaining provisions will continue in full force to the extent permitted by law.

25

No Waiver

Failure by Lettersiro to enforce any provision of this EULA on one occasion does not waive Lettersiro’s right to enforce that provision or another provision later.

26

Entire Agreement

This EULA, together with:

  • the license selected at purchase;
  • the applicable purchase/order details;
  • any specific product license terms;
  • and any written Custom or Corporate agreement,

constitutes the agreement governing use of the Font Software.

27
