Overview

What is Grimmory?

Grimmory is a self-hosted application for managing and reading books and comics (PDF, EPUB, CBZ), successor to Booklore. It offers a complete personal library: metadata editing, reading progress tracking, multi-user support with separate shelves and preferences, as well as a built-in reader for PDF and EPUB with annotations and highlighting.

The tool automatically enriches your catalog by fetching covers and information from Google Books and Open Library, and offers smart shelves with rule-based filtering. The BookDrop feature monitors a folder and automatically imports deposited files.

For mobility, Grimmory exposes an OPDS feed and syncs your reading with Kobo e-readers and the KOReader app, without relying on any third-party cloud service — your reading data remains yours.

Frequently asked questions

You might be wondering…

About Grimmory 6 questions

What file formats are supported?

Grimmory handles books and comics in PDF, EPUB, and CBZ formats, with a built-in reader for PDFs and EPUBs.

Can I sync my e-readers?

Yes. Grimmory is OPDS compatible and offers native synchronization with Kobo e-readers and the KOReader app, including reading progress.

Where is my data hosted?

On DINAO infrastructure in France, in one of the available data centers. Your books and history never leave the territory.

Can multiple people use it?

Yes. Grimmory is multi-user: each person has their own shelves, preferences, and reading progress on the same library.

How do I easily add my books?

Via BookDrop: drop your files into a monitored folder and Grimmory detects and automatically imports them, fetching the metadata.

Is this application tested before it is offered?

Yes. Version v3.5.0 was deployed on our infrastructure on 21 September 2026 and its start-up was checked automatically: every expected service must respond for this page to carry this statement. The deployment template used was last updated on 3 July 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.

Option 1Option 2Option 3 All offers 1 question

These answers apply to every offer on this page.

In which data centre is my service hosted?

In France, in DINAO's private racks within two third-party data centres: Free Pro in Marseille (MAR02) and Euclyde DC1 in Sophia-Antipolis. The operator provides the building, power, cooling and physical security; DINAO operates everything inside its racks, entirely and independently.

Option 1 Managed container 14 questions

These answers apply to the managed container. They do not apply to the VPS offers.

What exactly does the managed service cover?

DINAO's managed service is included in the price of your container. It covers the technical operation of the server and its software layers: operating system, database, runtime environment and application (installation, security updates, backups, monitoring). It does not include help with the day-to-day use of the application, which remains the customer's responsibility. It is provided on a best-effort basis, under an obligation of means: your requests are handled according to their nature and criticality, in the order of priority set by DINAO, taking particular account of the impact on service availability. No response or restoration time is guaranteed at this level. Technical monitoring is automatic, 24 hours a day, 7 days a week: an outage is detected without any action on your part. Human interventions take place Monday to Friday, excluding public holidays.

If your business needs a guaranteed response time, two “Support responsiveness” options can be taken out when ordering or during the contract:

– Priority handling (€15 excl. VAT/month): handling by a technician within 2 hours (guaranteed intervention time, GTI);
– Enhanced priority handling (€35 excl. VAT/month): handling within 30 minutes and restoration within 4 hours (GTI and guaranteed restoration time, GTR).

These times are counted only from 9 a.m. to 5 p.m., Monday to Friday, excluding public holidays. Time not elapsed at 5 p.m. resumes on the next working day: with a 2-hour GTI, a request received at 4:30 p.m. is handled at the latest at 10:30 a.m. on the next working day. The GTI guarantees the start of handling, not the resolution. For extended backup retention or a copy on a second site, contact our Application Container department.

How are application updates handled?

Major version upgrades are not included in managed services: they modify the application itself — data schema, extensions, configuration — and may render it inoperable. DINAO, however, offers a protected automatic update option: a full backup is taken, the new version is installed, and then the service startup is automatically verified. If the service does not restart correctly, the previous version and the backup are automatically restored — your application returns to its previous state. This option covers updates within your major version; moving to a higher major version remains your decision and may be subject to a support service.

If I change my application's address, does the old address continue to work?

Yes, for 24 hours: the old address automatically redirects (302, path preserved) to the new one, and then the redirect is removed. Before saving, the dashboard checks that the new address points to the container's server and indicates the DNS record to create if not; the client can also make the www variant respond. The HTTPS certificate is obtained automatically.

Do you provide on-call support outside of business hours?

Not contractually: automatic 24/7 monitoring, with human intervention on working days; out-of-hours intervention remains possible without commitment.

Is there a more committed managed services option than the one included?

Yes, upon request. The included managed services are provided on a "best effort" basis with no guaranteed response time. Extended managed services packages can be set up — including priority handling, extended intervention windows, time commitments, extended backup retention, and replication to a second site. Their content and pricing are determined on a case-by-case basis with the client: as of today, there is no public catalogue of packages or online-purchasable options. Requests should be submitted via the Application Container service (Support Department #12, conteneur@dinao.com).

What is the maximum data loss (RPO) and recovery time objective (RTO) for a container?

Daily backup: at worst, the previous day's data (up to 24 hours). Restoration initiated by the client from their client area, with no time commitment (depends on the volume).

Can I get priority handling for my support requests?

Yes, the "Support Responsiveness" option can be ordered on all four container plans, with three levels: "Best effort" (included, €0, no guaranteed response time), "Priority handling" (€15/month or €150/year) and "Priority handling + extended 8am-8pm window" (€35/month or €350/year). Priority is understood relative to requests from lower-tier customers: none of these levels include a guarantee of response time (RT) or resolution time (RT). Backup retention and off-site copy options are not yet available for ordering.

Can I start on the DINAO subdomain offered at the time of order, then switch to my own domain name later without reinstalling or losing my data?

Yes, at no cost. The "Domain" button in the client area replaces the container's address: the panel first checks that the new name points to the server (and indicates the DNS record to create if not), the HTTPS certificate is obtained automatically, the public address is passed to the application (PUBLIC_URL) and only the application container restarts — database, volumes and settings remain in place. The old address redirects to the new one for 24 hours, the www variant can be added. Moodle: files inserted by the editor follow; manually entered absolute links are updated with the "Find and Replace" tool.

I want to go directly from my version to the latest one, but an intermediate version changes what the application expects: what happens?

You can upgrade directly; the platform does not block you. Before launching the update, it shows you each breaking change encountered along the way (a mandatory variable to fill in, a data volume that is no longer read, a removed service, a new major version) and what needs to be done. A variable that is already filled in is indicated as done. You confirm once the changes are made; a backup is taken before the update, and if the new version does not start, the service automatically reverts to your previous version. The automatic update, however, never crosses such a change.

I receive the message 'automatic update blocked by security scan': what should I do?

Nothing is mandatory. Before each automatic update, the platform analyzes the new version; with the default setting, it never installs a version that has more vulnerabilities than the one currently in service. The current version continues to operate, backed up daily; the update will proceed automatically as soon as a published version is not less secure. The setting can be changed in the Security tab of the dashboard, with full awareness.

Can DINAO or an artificial intelligence tool access the data in my container?

DINAO does not administer the inside of the container and does not access application data, except upon explicit request from the customer as part of support (Containers conditions, art. 2); access is limited to those who need it and is logged (personal data appendix, §3). AI tools serve as aids for diagnosing incidents (logs, incident correlation, intervention proposals), always validated by an operator. When customer data is involved, models executed on DINAO's computing servers, located in France, take priority; a third-party provider receives only pseudonymised data (names, company names, addresses, phone numbers, domains replaced), does not use it to train its models, and limits its retention (Terms and Conditions, art. 5 bis). Data is never used to train a model. Upon request, DINAO indicates whether an AI was used for a request.

Are there any activation fees or mandatory options in addition to the container price?

No. The four plans (Discovery €9.90, Standard €19.90, Performance €39.90, Intensive €79.90 excl. VAT per month, with 20% VAT added) have no setup fees. The price includes hosting, infrastructure management, the application database, the HTTPS certificate, and daily backups. Options (support responsiveness, backups on request) are optional.

Can I host multiple applications on the same server so they can communicate with each other?

Yes: a private network can connect several of your applications, not just two, provided they are hosted on the same server (otherwise, a prior migration brings them closer). Each exposes the service of your choice under an internal name; you can add, remove, or dissolve the network at any time. If you want to freely assemble many containers with your own networks, a dedicated server (VPS) remains the suitable offering.

Can I choose the datacenter for my container?

Yes, at the time of order: no choice is made on your behalf. The datacenter is then displayed in your client area, in the service information.
